 177-379 4.41e-143

The ligand binding domain of the retinoid X receptor and Ultraspiracle, members of nuclear receptor superfamily; The ligand binding domain of the retinoid X receptor (RXR) and Ultraspiracle (USP): This family includes two evolutionary related nuclear receptors: retinoid X receptor (RXR) and Ultraspiracle (USP). RXR is a nuclear receptor in mammalian and USP is its counterpart in invertebrates. The native ligand of retinoid X receptor is 9-cis retinoic acid (RA). RXR functions as a DNA binding partner by forming heterodimers with other nuclear receptors including CAR, FXR, LXR, PPAR, PXR, RAR, TR, and VDR. RXRs can play different roles in these heterodimers. It acts either as a structural component of the heterodimer complex, required for DNA binding but not acting as a receptor or as both a structural and a functional component of the heterodimer, allowing 9-cis RA to signal through the corresponding heterodimer. In addition, RXR can also form homodimers, functioning as a receptor for 9-cis RA, independently of other nuclear receptors. Ultraspiracle (USP) plays similar roles as DNA binding partner of other nuclear rec eptors in invertebrates. USP has no known high-affinity ligand and is thought to be a silent component in the heterodimeric complex with partner receptors. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, RXR and USP have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

 80-156 4.07e-52

DNA-binding domain of retinoid X receptor (RXR) is composed of two C4-type zinc fingers; DNA-binding domain of retinoid X receptor (RXR) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. RXR functions as a DNA binding partner by forming heterodimers with other nuclear receptors including CAR, FXR, LXR, PPAR, PXR, RAR, TR, and VDR. All RXR heterodimers preferentially bind response elements composed of direct repeats of two AGGTCA sites with a 1-5 bp spacer. RXRs can play different roles in these heterodimers. RXR acts either as a structural component of the heterodimer complex, required for DNA binding but not acting as a receptor, or as both a structural and a functional component of the heterodimer, allowing 9-cis RA to signal through the corresponding heterodimer. In addition, RXR can also form homodimers, functioning as a receptor for 9-cis RA, independently of other nuclear receptors. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, RXR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

Ligand-binding domain of nuclear receptor family 2; Ligand-binding domain (LBD) of nuclear receptor (NR) family 2: This is one of the major subfamily of nuclear receptors, including some well known nuclear receptors such as glucocorticoid receptor (GR), mineralocorticoid receptor (MR), estrogen receptor (ER), progesterone receptor (PR), and androgen receptor (AR), other related receptors. Nuclear receptors form a superfamily of ligand-activated transcription regulators, which regulate various physiological functions, from development, reproduction, to homeostasis and metabolism in animals (metazoans). The family contains not only receptors for known ligands but also orphan receptors for which ligands do not exist or have not been identified. NRs share a common structural organization with a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of heptocyte nuclear factor 4, which is explosively expanded in nematodes; The ligand binding domain of hepatocyte nuclear factor 4 (HNF4) like proteins: HNF4 is a member of the nuclear receptor superfamily. HNF4 plays a key role in establishing and maintenance of hepatocyte differentiation in the liver. It is also expressed in gut, kidney, and pancreatic beta cells. HNF4 was originally classified as an orphan receptor, but later it is found that HNF4 binds with very high affinity to a variety of fatty acids. However, unlike other nuclear receptors, the ligands do not act as a molecular switch for HNF4. They seem to constantly bind to the receptor, which is constitutively active as a transcription activator. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, HNF4 has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD). The LBD domain is also responsible for recruiting co-activator proteins. More than 280 nuclear receptors are found in C. ele gans, most of which are originated from an explosive burst of duplications of HNF4.

Ligand binding domain of chicken ovalbumin upstream promoter transcription factors, a member of the nuclear receptor family; The ligand binding domain of chicken ovalbumin upstream promoter transcription factors (COUP-TFs): COUP-TFs are orphan members of the steroid/thyroid hormone receptor superfamily. They are expressed in many tissues and are involved in the regulation of several important biological processes, such as neurogenesis, organogenesis, cell fate determination, and metabolic homeostasis. In mammals two isoforms named COUP-TFI and COUP-TFII have been identified. Both genes show an exceptional homology and overlapping expression patterns, suggesting that they may serve redundant functions. Although COUP-TF was originally characterized as a transcriptional activator of the chicken ovalbumin gene, COUP-TFs are generally considered to be repressors of transcription for other nuclear hormone receptors, such as retinoic acid receptor (RAR), thyroid hormone receptor (TR), vitamin D receptor (VDR), peroxisome proliferator activated receptor (PPAR), and hepatocyte nuclear factor 4 (HNF4). Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, COUP-TFs have a central well cons erved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

 80-156 4.07e-52

DNA-binding domain of retinoid X receptor (RXR) is composed of two C4-type zinc fingers; DNA-binding domain of retinoid X receptor (RXR) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. RXR functions as a DNA binding partner by forming heterodimers with other nuclear receptors including CAR, FXR, LXR, PPAR, PXR, RAR, TR, and VDR. All RXR heterodimers preferentially bind response elements composed of direct repeats of two AGGTCA sites with a 1-5 bp spacer. RXRs can play different roles in these heterodimers. RXR acts either as a structural component of the heterodimer complex, required for DNA binding but not acting as a receptor, or as both a structural and a functional component of the heterodimer, allowing 9-cis RA to signal through the corresponding heterodimer. In addition, RXR can also form homodimers, functioning as a receptor for 9-cis RA, independently of other nuclear receptors. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, RXR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of nuclear receptors is composed of two C4-type zinc fingers; DNA-binding domain of nuclear receptors is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. It interacts with a specific DNA site upstream of the target gene and modulates the rate of transcriptional initiation. Nuclear receptors form a superfamily of ligand-activated transcription regulators, which regulate various physiological functions, from development, reproduction, to homeostasis and metabolism in animals (metazoans). The family contains not only receptors for known ligands but also orphan receptors for which ligands do not exist or have not been identified. NRs share a common structural organization with a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD). Most nuclear receptors bind as homodimers or heterodimers to their target sites, which consist of two hexameric half-sites. Specificity is determined by the half-site sequence, the relative orientation of the half-sites and the number of spacer nucleotides between the half-sites. However, a growing number of nuclear receptors have been reported to bind to DNA as monomers.

The ligand binding domain of FTZ-F1 like nuclear receptors; The ligand binding domain of FTZ-F1 like nuclear receptors: This nuclear receptor family includes at least three subgroups of receptors that function in embryo development and differentiation, and other processes. FTZ-F1 interacts with the cis-acting DNA motif of ftz gene, which required at several stages of development. Particularly, FTZ-F1 genes are strongly linked to steroid biosynthesis and sex-determination; LRH-1 is a regulator of bile-acid homeostasis, steroidogenesis, reverse cholesterol transport and the initial stages of embryonic development. SF-1 is an essential regulator of endocrine development and function and is considered a master regulator of reproduction; SF-1 functions cooperatively with other transcription factors to modulate gene expression. Phospholipids have been identified as potential ligand for LRH-1 and steroidogenic factor-1 (SF-1). However, the ligand for FTZ-F1 has not yet been identified. Most nuclear receptors function as homodimer or heterodimers. However, LRH-1 and SF-1 bind to DNA as a monomer. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, receptors in this family have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of estrogen receptor and estrogen receptor-related receptors; The ligand binding domain of estrogen receptor (ER) and estrogen receptor-related receptors (ERRs): Estrogen receptors are a group of receptors which are activated by the hormone estrogen. Estrogen regulates many physiological processes including reproduction, bone integrity, cardiovascular health, and behavior. The main mechanism of action of the estrogen receptor is as a transcription factor by binding to the estrogen response element of target genes upon activation by estrogen and then recruiting coactivator proteins which are responsible for the transcription of target genes. Additionally some ERs may associate with other membrane proteins and can be rapidly activated by exposure of cells to estrogen. ERRs are closely related to the estrogen receptor (ER) family. But, it lacks the ability to bind estrogen. ERRs can interfere with the classic ER-mediated estrogen signaling pathway, positively or negatively. ERRs share target genes, co-regulators and promoters with the estrogen receptor (ER) family. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, ER and ERRs have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

 81-158 6.37e-40

DNA-binding domain of thyroid hormone receptors (TRs) is composed of two C4-type zinc fingers; DNA-binding domain of thyroid hormone receptors (TRs) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. TR interacts with the thyroid response element, which is a DNA site with direct repeats of the consensus sequence 5'-AGGTCA-3' separated by one to five base pairs, upstream of target genes and modulates the rate of transcriptional initiation. Thyroid hormone receptor (TR) mediates the actions of thyroid hormones, which play critical roles in growth, development, and homeostasis in mammals. They regulate overall metabolic rate, cholesterol and triglyceride levels, and heart rate, and affect mood. TRs are expressed from two separate genes (alpha and beta) in human and each gene generates two isoforms of the receptor through differential promoter usage or splicing. TRalpha functions in the heart to regulate heart rate and rhythm and TRbeta is active in the liver and other tissues. The unliganded TRs function as transcription repressors, by binding to thyroid hormone response elements (TRE) predominantly as homodimers, or as heterodimers with retinoid X-receptors (RXR), and being associated with a complex of proteins containing corepressor proteins. Ligand binding promotes corepressor dissociation and binding of a coactivator to activate transcription. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, TR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of the TR2 and TR4 (human testicular receptor 2 and 4) is composed of two C4-type zinc fingers; DNA-binding domain of the TR2 and TR4 (human testicular receptor 2 and 4) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. TR2 and TR4 interact with specific DNA sites upstream of the target gene and modulate the rate of transcriptional initiation. TR4 and TR2 are orphan nuclear receptors; the physiological ligand is as yet unidentified. TR2 is abundantly expressed in the androgen-sensitive prostate. TR4 transcripts are expressed in many tissues, including central nervous system, adrenal gland, spleen, thyroid gland, and prostate. It has been shown that human TR2 binds to a wide spectrum of natural hormone response elements (HREs) with distinct affinities suggesting that TR2 may cross-talk with other gene expression regulation systems. The genes responding to TR2 or TR4 include genes that are regulated by retinoic acid receptor, vitamin D receptor, and peroxisome proliferator-activated receptor. TR4/2 binds to HREs as dimers. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, TR2-like receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of heptocyte nuclear factor 4 (HNF4) is composed of two C4-type zinc fingers; DNA-binding domain of hepatocyte nuclear factor 4 (HNF4) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. HNF4 interacts with a DNA site, composed of two direct repeats of AGTTCA with 1 bp spacer, which is upstream of target genes and modulates the rate of transcriptional initiation. HNF4 is a member of the nuclear receptor superfamily. HNF4 plays a key role in establishing and maintenance of hepatocyte differentiation in the liver. It is also expressed in gut, kidney, and pancreatic beta cells. HNF4 was originally classified as an orphan receptor, but later it is found that HNF4 binds with very high affinity to a variety of fatty acids. However, unlike other nuclear receptors, the ligands do not act as a molecular switch for HNF4. They seem to constantly bind to the receptor, which is constitutively active as a transcription activator. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, HNF4 has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of the orphan nuclear receptor, nerve growth factor-induced-B; DNA-binding domain (DBD) of the orphan nuclear receptor, nerve growth factor-induced-B (NGFI-B) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. NGFI-B interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. NGFI-B is a member of the nuclear-steroid receptor superfamily. NGFI-B is classified as an orphan receptor because no ligand has yet been identified. NGFI-B is an early immediate gene product of embryo development that is rapidly produced in response to a variety of cellular signals including nerve growth factor. It is involved in T-cell-mediated apoptosis, as well as neuronal differentiation and function. NGFI-B regulates transcription by binding to a specific DNA target upstream of its target genes and regulating the rate of transcriptional initiation. NGFI-B binds to the NGFI-B response element (NBRE) 5'-(A/T)AAAGGTCA as a monomer. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, NGFI-B has a central well-conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. This domain interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. This nuclear receptor family includes at least three subgroups of receptors that function in embryo development and differentiation, and other processes. FTZ-F1 interacts with the cis-acting DNA motif of ftz gene, which is required at several stages of development. Particularly, FTZ-F1 regulated genes are strongly linked to steroid biosynthesis and sex-determination; LRH-1 is a regulator of bile-acid homeostasis, steroidogenesis, reverse cholesterol transport and the initial stages of embryonic development; SF-1 is an essential regulator of endocrine development and function and is considered a master regulator of reproduction; SF-1 functions cooperatively with other transcription factors to modulate gene expression. Phospholipids have been identified as potential ligand for LRH-1 and steroidogenic factor-1 (SF-1). However, the ligand for FTZ-F1 has not yet been identified. Most nuclear receptors function as homodimer or heterodimers. However, LRH-1 and SF-1 bind to DNA as monomers. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, receptors in this family have a central well conserved DNA-binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of ecdysone-induced DHR4 orphan nuclear receptor is composed of two C4-type zinc fingers; DNA-binding domain of ecdysone-induced DHR4 orphan nuclear receptor is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. This domain interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. Ecdysone-induced orphan receptor DHR4 is a member of the nuclear receptor family. DHR4 is expressed during the early Drosophila larval development and is induced by ecdysone. DHR4 coordinates growth and maturation in Drosophila by mediating endocrine response to the attainment of proper body size during larval development. Mutations in DHR4 result in shorter larval development which translates into smaller and lighter flies. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, DHR4 has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of nuclear receptor steroidogenic factor 1, a member of nuclear receptor superfamily; The ligand binding domain of nuclear receptor steroidogenic factor 1 (SF-1): SF-1, a member of the nuclear hormone receptor superfamily, is an essential regulator of endocrine development and function and is considered a master regulator of reproduction. Most nuclear receptors function as homodimer or heterodimers, however SF-1 binds to its target genes as a monomer, recognizing the variations of the DNA sequence motif, T/CCA AGGTCA. SF-1 functions cooperatively with other transcription factors to modulate gene expression. Phospholipids have been determined as potential ligands of SF-1. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, SF-1 has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. ROR interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. RORS are key regulators of many physiological processes during embryonic development. RORs bind as monomers to specific ROR response elements (ROREs) consisting of the consensus core motif AGGTCA preceded by a 5-bp A/T-rich sequence. There are three subtypes of retinoid-related orphan receptors (RORs), alpha, beta, and gamma, which differ only in N-terminal sequence and are distributed in distinct tissues. RORalpha plays a key role in the development of the cerebellum particularly in the regulation of the maturation and survival of Purkinje cells. RORbeta expression is largely restricted to several regions of the brain, the retina, and pineal gland. RORgamma is essential for lymph node organogenesis. Recently, it has been suggested that cholesterol or a cholesterol derivative are the natural ligands of RORalpha. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, retinoid-related orphan receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of the orphan nuclear receptors TR4 and TR2; The ligand binding domain of the TR4 and TR2 (human testicular receptor 4 and 2): TR4 and TR2 are orphan nuclear receptors. Several isoforms of TR4 and TR2 have been isolated in various tissues. TR2 is abundantly expressed in the androgen-sensitive prostate. TR4 transcripts are expressed in many tissues, including central nervous system, adrenal gland, spleen, thyroid gland, and prostate. The expression of TR2 is negatively regulated by androgen, retinoids, and radiation. The expression of both mouse TR2 and TR4 is up-regulated by neurocytokine ciliary neurotrophic factor (CNTF) in mouse. It has shown that human TR2 binds to a wide spectrum of natural hormone response elements (HREs) with distinct affinities suggesting that TR2 may cross-talk with other gene expression regulation systems. The genes responding to TR2 or TR4 include genes that are regulated by retinoic acid receptor, vitamin D receptor, peroxisome proliferator-activated receptor. TR4/2 binds to HREs as a dimer. Like other members of the nuclea r receptor (NR) superfamily of ligand-activated transcription factors, TR2-like receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of estrogen receptor-related nuclear receptors; The ligand binding domain of estrogen receptor-related receptors (ERRs): The family of estrogen receptor-related receptors (ERRs), a subfamily of nuclear receptors, is closely related to the estrogen receptor (ER) family, but it lacks the ability to bind estrogen. ERRs can interfere with the classic ER-mediated estrogen signaling pathway, positively or negatively. ERRs share target genes, co-regulators and promoters with the estrogen receptor (ER) family. There are three subtypes of ERRs: alpha, beta and gamma. ERRs bind at least two types of DNA sequence, the estrogen response element and another site, originally characterized as SF-1 (steroidogenic factor 1) response element. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, ERR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of orphan nuclear receptor Ecdysone-induced receptor DHR4; The ligand binding domain of Ecdysone-induced receptor DHR4: Ecdysone-induced orphan receptor DHR4 is a member of the nuclear receptor family. DHR4 is expressed during the early Drosophila larval development and is induced by ecdysone. DHR4 coordinates growth and maturation in Drosophila by mediating endocrine response to the attainment of proper body size during larval development. Mutations in DHR4 result in shorter larval development which translates into smaller and lighter flies. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, DHR4 has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of Drosophila ecdysone-induced protein 78 (E78) like is composed of two C4-type zinc fingers; DNA-binding domain of proteins similar to Drosophila ecdysone-induced protein 78 (E78) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. E78 interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. Drosophila ecdysone-induced protein 78 (E78) is a transcription factor belonging to the nuclear receptor superfamily. E78 is a product of the ecdysone-inducible gene found in an early late puff locus at position 78C during the onset of Drosophila metamorphosis. An E78 orthologue from the Platyhelminth Schistosoma mansoni (SmE78) has also been identified. It is the first E78 orthologue known outside of the molting animals--the Ecdysozoa. The SmE78 may be involved in transduction of an ecdysone signal in S. mansoni, consistent with its function in Drosophila. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, E78-like receptors have a central well conserved DNA-binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. PNR interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. This family includes nuclear receptor Tailless (TLX), photoreceptor cell-specific nuclear receptor (PNR) and related receptors. TLX is an orphan receptor that plays a key role in neural development by regulating cell cycle progression and exit of neural stem cells in the developing brain. PNR is expressed only in the outer layer of retinal photoreceptor cells. It may be involved in the signaling pathway regulating photoreceptor differentiation and/or maintenance. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, PNR-like receptors have a central well-conserved DNA-binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

Ligand binding domain of Estrogen receptor, which are activated by the hormone 17beta-estradiol (estrogen); The ligand binding domain (LBD) of Estrogen receptor (ER): Estrogen receptor, a member of nuclear receptor superfamily, is activated by the hormone estrogen. Estrogen regulates many physiological processes including reproduction, bone integrity, cardiovascular health, and behavior. The main mechanism of action of the estrogen receptor is as a transcription factor by binding to the estrogen response element of target genes upon activation by estrogen and then recruiting coactivator proteins which are responsible for the transcription of target genes. Additionally some ERs may associate with other membrane proteins and can be rapidly activated by exposure of cells to estrogen. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, ER has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD). The C-terminal LBD also contains AF-2 activation motif, the dimerization motif, and part of the nuclear localization region. Estrogen receptor has been linked to aging, cancer, obesity and other diseases.

Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. This domain interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. REV-ERB receptors are transcriptional regulators belonging to the nuclear receptor superfamily. They regulate a number of physiological functions including the circadian rhythm, lipid metabolism, and cellular differentiation. REV-ERB receptors bind as a monomer to a (A/G)GGTCA half-site with a 5' AT-rich extension or as a homodimer to a direct repeat 2 element (AGGTCA sequence with a 2-bp spacer), indicating functional diversity. When bound to the DNA, they recruit corepressors (NcoR/histone deacetylase 3) to the promoter, resulting in repression of the target genes. The porphyrin heme has been demonstrated to function as a ligand for REV-ERB receptor. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, REV-ERB receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

The DNA-binding domain of vitamin D receptors (VDR) like nuclear receptor family is composed of two C4-type zinc fingers; The DNA-binding domain of vitamin D receptors (VDR) like nuclear receptor family is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. This domain interacts with specific DNA site upstream of the target gene and modulates the rate of transcriptional initiation. This family includes three types of nuclear receptors: vitamin D receptors (VDR), constitutive androstane receptor (CAR) and pregnane X receptor (PXR). VDR regulates calcium metabolism, cellular proliferation and differentiation. PXR and CAR function as sensors of toxic byproducts of cell metabolism and of exogenous chemicals, to facilitate their elimination. The DNA binding activity is regulated by their corresponding ligands. VDR is activated by Vitamin D; CAR and PXR respond to a diverse array of chemically distinct ligands, including many endogenous compounds and clinical drugs. Like other nuclear receptors, xenobiotic receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. EcR interacts with highly degenerate pseudo-palindromic response elements, resembling inverted repeats of 5'-AGGTCA-3' separated by 1 bp, upstream of the target gene and modulates the rate of transcriptional initiation. EcR is present only in invertebrates and regulates the expression of a large number of genes during development and reproduction. EcR functions as a heterodimer by partnering with ultraspiracle protein (USP), the ortholog of the vertebrate retinoid X receptor (RXR). The natural ligands of EcR are ecdysteroids, the endogenous steroidal hormones found in invertebrates. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, EcRs have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

 217-395 7.21e-25

The ligand binding domain (LBD) of retinoic acid receptor (RAR), a members of the nuclear receptor superfamily; The ligand binding domain (LBD) of retinoic acid receptor (RAR): Retinoic acid receptors are members of the nuclear receptor (NR) superfamily of ligand-regulated transcription factors. RARs mediate the biological effect of retinoids, including both naturally dietary vitamin A (retinol) metabolites and active synthetic analogs. Retinoids play key roles in a wide variety of essential biological processes, such as vertebrate embryonic morphogenesis and organogenesis, differentiation and apoptosis, and homeostasis. RARs function as heterodimers with retinoic X receptors by binding to specific RAR response elements (RAREs) found in the promoter regions of retinoid target genes. In the absence of ligand, the RAR-RXR heterodimer recruits the corepressor proteins NCoR or AMRT, and associated factors such as histone deacetylases or DNA-methyltransferases, leading to an inactive condensed chromatin structure, preventing transcription. Upon ligand binding, the corepressors are released, and coactivator complexes such as histone acetyltransferase or histone arginine methyltransferases are recruited to activate transcription. There are three RAR subtypes (alpha, beta, gamma), originating from three distinct genes. For each subtype, several isoforms exist that differ in their N-terminal region, allowing retinoids to exert their pleiotropic effects. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, retinoic acid receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of Liver X receptors (LXRs) family is composed of two C4-type zinc fingers; DNA-binding domain of Liver X receptors (LXRs) family is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. LXR interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. LXR operates as cholesterol sensor which protects cells from cholesterol overload by stimulating reverse cholesterol transport from peripheral tissues to the liver and its excretion in the bile. Oxidized cholesterol derivatives or oxysterols were identified as specific ligands for LXRs. LXR functions as a heterodimer with the retinoid X receptor (RXR) which may be activated by either LXR agonist or 9-cis retinoic acid, a specific RXR ligand. The LXR/RXR complex binds to a liver X receptor response element (LXRE) in the promoter region of target genes. The ideal LXRE sequence is a direct repeat-4 (DR-4) DNA fragment consisting of two AGGTCA hexameric half-sites separated by a 4-nucleotide spacer. LXR has typical NR modular structure with a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and the ligand binding domain (LBD) at the C-terminal.

The ligand binding domain of REV-ERB receptors, members of the nuclear receptor superfamily; The ligand binding domain (LBD) of REV-ERB receptors: REV-ERBs are transcriptional regulators belonging to the nuclear receptor superfamily. They regulate a number of physiological functions including the circadian rhythm, lipid metabolism, and cellular differentiation. The LBD domain of REV-ERB is unusual in the nuclear receptor family by lacking the AF-2 region that is responsible for coactivator interaction. REV-ERBs act as constitutive repressors because of their inability to bind coactivators. REV-ERB receptors can bind to two classes of DNA response elements as either a monomer or heterodimer, indicating functional diversity. When bound to the DNA, they recruit corepressors (NcoR/histone deacetylase 3) to the promoter, resulting in repression of the target gene. The porphyrin heme has been demonstrated to function as a ligand for REV-ERB. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, REV-ERB receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of Nurr1 and related nuclear receptor proteins, members of nuclear receptor superfamily; The ligand binding domain of nuclear receptor Nurr1_like: This family of nuclear receptors, including Nurr1, Nerve growth factor-induced-B (NGFI-B) and DHR38 are involved in the embryo development. Nurr1 is a transcription factor that is expressed in the embryonic ventral midbrain and is critical for the development of dopamine (DA) neurons. Structural studies have shown that the ligand binding pocket of Nurr1 is filled by bulky hydrophobic residues, making it unable to bind to ligands. Therefore, it belongs to the class of orphan receptors. However, Nurr1 forms heterodimers with RXR and can promote signaling via its partner, RXR. NGFI-B is an early immediate gene product of embryo development that is rapidly produced in response to a variety of cellular signals including nerve growth factor. It is involved in T-cell-mediated apoptosis, as well as neuronal differentiation and function. NGFI-B regulates transcription by binding to a specific DNA target upstream of its target genes and regulating the rate of tr anscriptional initiation. Another group of receptor in this family is DHR38. DHR38 is the Drosophila homolog to the vertebrate NGFI-B-type orphan receptor. It interacts with the USP component of the ecdysone receptor complex, suggesting that DHR38 might modulate ecdysone-triggered signals in the fly, in addition to the ECR/USP pathway. Nurr1_like proteins exhibit a modular structure that is characteristic for nuclear receptors; they have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

DNA-binding domain of vitamin D receptors (VDR) is composed of two C4-type zinc fingers; DNA-binding domain of vitamin D receptors (VDR) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. VDR interacts with a VDR response element, a direct repeat of GGTTCA DNA site with 3 bp spacer upstream of the target gene, and modulates the rate of transcriptional initiation. VDR is a member of the nuclear receptor (NR) superfamily that functions as classical endocrine receptors. VDR controls a wide range of biological activities including calcium metabolism, cell proliferation and differentiation, and immunomodulation. VDR is a high-affinity receptor for the biologically most active Vitamin D metabolite, 1alpha,25-dihydroxyvitamin D3 (1alpha,25(OH)2D3). The binding of the ligand to the receptor induces a conformational change of the ligand binding domain (LBD) with consequent dissociation of corepressors. Upon ligand binding, VDR forms a heterodimer with the retinoid X receptor (RXR) that binds to vitamin D response elements (VDREs), recruits coactivators. This leads to the expression of a large number of genes. Approximately 200 human genes are considered to be primary targets of VDR and even more genes are regulated indirectly. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, VDR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of DAX1 protein, a nuclear receptor lacking DNA binding domain; The ligand binding domain of the DAX1 protein: DAX1 (dosage-sensitive sex reversal adrenal hypoplasia congenita critical region on chromosome X gene 1) is a nuclear receptor with a typical ligand binding domain, but lacks the DNA binding domain. DAX1 plays an important role in the normal development of several hormone-producing tissues. Duplications of the region of the X chromosome containing DAX1 cause dosage sensitive sex reversal. DAX1 acts as a global repressor of many nuclear receptors, including SF-1, LRH-1, ERR, ER, AR and PR. DAX1 can form homodimer and heterodimerizes with its alternatively spliced isoform DAX1A and other nuclear receptors such as SHP, ERalpha and SF-1.

The ligand binding domain of DAX1 protein, a nuclear receptor lacking DNA binding domain; The ligand binding domain of DAX1-like proteins: This orphan nuclear receptor family includes DAX1 (dosage-sensitive sex reversal adrenal hypoplasia congenita critical region on chromosome X gene 1) and the Small Heterodimer Partner (SHP). Both receptors have a typical ligand binding domain, but lack the DNA binding domain, typical to almost all of the nuclear receptors. They function as a transcriptional coregulator by directly interacting with other nuclear receptors. DAX1 and SHP can form heterodimers with each other, as well as with many other nuclear receptors. In addition, DAX1 can also form homodimers. DAX1 plays an important role in the normal development of several hormone-producing tissues. SHP has shown to regulate a variety of target genes.

DNA-binding domain of constitutive androstane receptor (CAR) is composed of two C4-type zinc fingers; DNA-binding domain (DBD) of constitutive androstane receptor (CAR) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. CAR DBD interacts with CAR response element, a perfect repeat of two AGTTCA motifs with a 4 bp spacer upstream of the target gene, and modulates the rate of transcriptional initiation. The constitutive androstane receptor (CAR) is a ligand-regulated transcription factor that responds to a diverse array of chemically distinct ligands, including many endogenous compounds and clinical drugs. It functions as a heterodimer with RXR. The CAR/RXR heterodimer binds many common response elements in the promoter regions of a diverse set of target genes involved in the metabolism, transport, and ultimately, elimination of these molecules from the body. CAR is a closest mammalian relative of PXR and is activated by some of the same ligands as PXR and regulates a subset of common genes. The sequence homology and functional similarity suggests that the CAR gene arose from a duplication of an ancestral PXR gene. Like other nuclear receptors, CAR has a central well conserved DNA binding domain, a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain.

The ligand binding domain of Retinoid-related orphan receptors, of the nuclear receptor superfamily; The ligand binding domain (LBD) of Retinoid-related orphan receptors (RORs): Retinoid-related orphan receptors (RORs) are transcription factors belonging to the nuclear receptor superfamily. RORs are key regulators of many physiological processes during embryonic development. RORs bind as monomers to specific ROR response elements (ROREs) consisting of the consensus core motif AGGTCA preceded by a 5-bp A/T-rich sequence. Transcription regulation by RORs is mediated through certain corepressors, as well as coactivators. There are three subtypes of retinoid-related orphan receptors (RORs), alpha, beta, and gamma that differ only in N-terminal sequence and are distributed in distinct tissues. RORalpha plays a key role in the development of the cerebellum, particularly in the regulation of the maturation and survival of Purkinje cells. RORbeta expression is largely restricted to several regions of the brain, the retina, and pineal gland. RORgamma is essential for lymph node organogenesis. Recently, it has been su ggested that cholesterol or a cholesterol derivative is the natural ligand of RORalpha. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, retinoid-related orphan receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of Nurr1, a member of conserved family of nuclear receptors; The ligand binding domain of nuclear receptor Nurr1: Nurr1 belongs to the conserved family of nuclear receptors. It is a transcription factor that is expressed in the embryonic ventral midbrain and is critical for the development of dopamine (DA) neurons. Structural studies have shown that the ligand binding pocket of Nurr1 is filled by bulky hydrophobic residues, making it unable to bind to ligands. Therefore, it belongs to the class of orphan receptors. However, Nurr1 forms heterodimers with RXR and can promote signaling via its partner, RXR. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, Nurr1 has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

The DNA binding domain of GR_like nuclear receptors is composed of two C4-type zinc fingers; The DNA binding domain of GR_like nuclear receptors is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. It interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. This family of NRs includes four types of nuclear hormone receptors: glucocorticoid receptor (GR), mineralocorticoid receptor (MR), progesterone receptor (PR), and androgen receptor (AR). The receptors bind to common DNA elements containing a partial palindrome of the core sequence 5'-TGTTCT-3' with a 3bp spacer. These four receptors regulate some of the most fundamental physiological functions such as the stress response, metabolism, electrolyte homeostasis, immune function, growth, development, and reproduction. The NRs in this family have high sequence homology and share similar functional mechanisms. The dominant mechanism of function is by direct DNA binding and transcriptional regulation of target genes . The GR, MR, PR, and AR exhibit same modular structure. They have a central highly conserved DNA binding domain (DBD), a non-conserved N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain of Liver X receptors, a family of nuclear receptors of ligand-activated transcription factors; The ligand binding domain of Liver X receptors: Liver X receptors (LXRs) belong to a family of nuclear receptors of ligand-activated transcription factors. LXRs operate as cholesterol sensors which protect from cholesterol overload by stimulating reverse cholesterol transport from peripheral tissues to the liver and its excretion in the bile. Oxidized cholesterol derivatives or oxysterols were identified as specific ligands for LXRs. Upon ligand binding a conformational change leads to recruitment of co-factors, which stimulates expression of target genes. Among the LXR target genes are several genes involved in cholesterol efflux from peripheral tissues such as the ATP-binding-cassette transporters ABCA1, ABCG1 and ApoE. There are two LXR isoforms in mammals, LXRalpha and LXRbeta. LXRalpha is expressed mainly in the liver, intestine, kidney, spleen, and adipose tissue, whereas LXRbeta is ubiquitously expressed at lower level. Both LXRalpha and LXRbeta function as heterodimers with the retinoid X receptor (RX R) which may be activated by either LXR ligands or 9-cis retinoic acid, a specific RXR ligand. The LXR/RXR complex binds to a liver X receptor response element (LXRE) in the promoter region of target genes. LXR has typical NR modular structure with a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and the ligand binding domain (LBD) at the C-terminal.

The ligand binding domain of peroxisome proliferator-activated receptors; The ligand binding domain (LBD) of peroxisome proliferator-activated receptors (PPAR): Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear receptor superfamily of ligand-activated transcription factors. PPARs play important roles in regulating cellular differentiation, development and lipid metabolism. Activated PPAR forms a heterodimer with the retinoid X receptor (RXR) that binds to the hormone response element located upstream of the peroxisome proliferator responsive genes and interacts with co-activators. There are three subtypes of peroxisome proliferator activated receptors, alpha, beta (or delta), and gamma, each with a distinct tissue distribution. Several essential fatty acids, oxidized lipids and prostaglandin J derivatives can bind and activate PPAR. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, PPAR has a central well conserved DNA binding domain (DBD), a variable N-terminal regulatory domain, a flexible hinge a nd a C-terminal ligand binding domain (LBD).

 175-368 1.39e-16

The ligand binding domain of thyroid hormone receptor, a members of a superfamily of nuclear receptors; The ligand binding domain (LBD) of thyroid hormone receptors: Thyroid hormone receptors are members of a superfamily of nuclear receptors. Thyroid hormone receptors (TR) mediate the actions of thyroid hormones, which play critical roles in growth, development, and homeostasis in mammals. They regulate overall metabolic rate, cholesterol and triglyceride levels, and heart rate, and affect mood. TRs are expressed from two separate genes (alpha and beta) in human and each gene generates two isoforms of the receptor through differential promoter usage or splicing. TRalpha functions in the heart to regulate heart rate and rhythm and TRbeta is active in the liver and other tissues. The unliganded TRs function as transcription repressors, by binding to thyroid hormone response elements (TRE) predominantly as homodimers, or as heterodimers with retinoid X-receptors (RXR), and being associated with a complex of proteins containing corepressor proteins. Ligand binding promotes corepressor dissociation and binding of a coactivator to activate transcription. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, TR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

 82-147 5.64e-16

DNA-binding domain of androgen receptor (AR) is composed of two C4-type zinc fingers; DNA-binding domain of androgen receptor (AR) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which co-ordinates a single zinc atom. To regulate gene expression, AR interacts with a palindrome of the core sequence 5'-TGTTCT-3' with a 3-bp spacer. It also binds to the direct repeat 5'-TGTTCT-3' hexamer in some androgen controlled genes. AR is activated by the androgenic hormones, testosterone or dihydrotestosterone, which are responsible for primary and for secondary male characteristics, respectively. The primary mechanism of action of ARs is by direct regulation of gene transcription. The binding of androgen results in a conformational change in the androgen receptor which causes its transport from the cytosol into the cell nucleus, and dimerization. The receptor dimer binds to a hormone response element of AR regulated genes and modulates their expression. Another mode of action of androgen receptor is independent of their interactions with DNA. The receptor interacts directly with signal transduction proteins in the cytoplasm, causing rapid changes in cell function, such as ion transport. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, AR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

E78 is a product of the ecdysone-inducible gene found in an early late puff locus at position 78C during the onset of Drosophila metamorphosis. Two isoforms of E78, E78A and E78B, are expressed from two nested transcription units. An E78 orthologue from the Platyhelminth Schistosoma mansoni (SmE78) has also been identified. It is the first E78 orthologue known outside of the molting animals--the Ecdysozoa. SmE78 may be involved in transduction of an ecdysone signal in S. mansoni, consistent with its function in Drosophila. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, E78-like receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

The ligand binding domain (LBD) of the Ecdysone receptor, a member of the nuclear receptors super family; The ligand binding domain (LBD) of the ecdysone receptor: The ecdysone receptor (EcR) belongs to the superfamily of nuclear receptors (NRs) of ligand-dependent transcription factors. Ecdysone receptor is present only in invertebrates and regulates the expression of a large number of genes during development and reproduction. ECR functions as a heterodimer by partnering with ultraspiracle protein (USP), the ortholog of the vertebrate retinoid X receptor (RXR). The natural ligands of ecdysone receptor are ecdysteroids#the endogenous steroidal hormones found in invertebrates. In addition, insecticide bisacylhydrazine used against pests has shown to act on EcR. EcR must be dimerised with a USP for high-affinity ligand binding to occur. The ligand binding triggers a conformational change in the C-terminal part of the EcR ligand-binding domain that leads to transcriptional activation of genes controlled by EcR. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, ec dysone receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

 209-367 3.63e-13

The ligand binding domain of Farnesoid X receptor:a member of the nuclear receptor superfamily of ligand-activated transcription factors; The ligand binding domain (LBD) of Farnesoid X receptor: Farnesoid X receptor (FXR) is a member of the nuclear receptor superfamily of ligand-activated transcription factors. FXR is highly expressed in the liver, the intestine, the kidney, and the adrenals. FXR plays key roles in the regulation of bile acid, cholesterol, triglyceride, and glucose metabolism. Evidences show that it also regulates liver regeneration. Upon binding of ligands, such as bile acid, an endogenous ligand, FXRs bind to FXR response elements (FXREs) either as a monomer or as a heterodimer with retinoid X receptor (RXR), and regulate the expression of various genes involved in bile acid, lipid, and glucose metabolism. There are two FXR genes (FXRalpha and FXRbeta) in mammals. A single FXRalpha gene encodes four isoforms resulting from differential use of promoters and alternative splicing. FXRbeta is a functional receptor in mice, rats, rabbits and dogs, but is a pseudogene in humans and primates. Like other members of the nuclear receptor (NR) superfamily, farnesoid X receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain (LBD).

 183-332 1.40e-09

Ligand binding domain of nuclear hormone receptors:glucocorticoid receptor, mineralocorticoid receptor , progesterone receptor, and androgen receptor; The ligand binding domain of GR_like nuclear receptors: This family of NRs includes four distinct, but closely related nuclear hormone receptors: glucocorticoid receptor (GR), mineralocorticoid receptor (MR), progesterone receptor (PR), and androgen receptor (AR). These four receptors play key roles in some of the most fundamental physiological functions such as the stress response, metabolism, electrolyte homeostasis, immune function, growth, development, and reproduction. The NRs in this family use multiple signaling pathways and share similar functional mechanisms. The dominant signaling pathway is via direct DNA binding and transcriptional regulation of target genes. Another mechanism is via protein-protein interactions, mainly with other transcription factors such as nuclear factor-kappaB and activator protein-1, to regulate gene expression patterns. Both pathways can up-regulate or down-regulate gene expression and require ligand activation of the receptor and recruitment of other cofactors such as chaperone proteins and coregulator proteins. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, GR, MR, PR, and AR share the same modular structure with a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

 180-377 9.12e-09

Ligand binding domain of the mineralocorticoid receptor, a member of the nuclear receptor superfamily; The ligand binding domain of the mineralocorticoid receptor (MR): MR, also called aldosterone receptor, is a member of nuclear receptor superfamily involved in the regulation of electrolyte and fluid balance. The receptor is activated by mineralocorticoids such as aldosterone and deoxycorticosterone as well as glucocorticoids, like cortisol and cortisone. Binding of its ligand results in its translocation to the cell nucleus, homodimerization and binding to hormone response elements (HREs) present in the promoter of MR controlled genes. This results in the recruitment of the coactivators and the transcription of the activated genes. MR is expressed in many tissues and its activation results in the expression of proteins regulating electrolyte and fluid balance. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, MR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD ). The LBD, in addition to binding ligand, contains a ligand-dependent activation function-2 (AF-2).

 215-367 3.58e-08

The ligand binding domain of xenobiotic receptors:pregnane X receptor and constitutive androstane receptor; The ligand binding domain of xenobiotic receptors: This xenobiotic receptor family includes pregnane X receptor (PXR), constitutive androstane receptor (CAR) and other related nuclear receptors. They function as sensors of toxic byproducts of cell metabolism and of exogenous chemicals, to facilitate their elimination. The nuclear receptor pregnane X receptor (PXR) is a ligand-regulated transcription factor that responds to a diverse array of chemically distinct ligands, including many endogenous compounds and clinical drugs. The ligand binding domain of PXR shows remarkable flexibility to accommodate both large and small molecules. PXR functions as a heterodimer with retinoic X receptor-alpha (RXRa) and binds to a variety of response elements in the promoter regions of a diverse set of target genes involved in the metabolism, transport, and elimination of these molecules from the cell. Constitutive androstane receptor (CAR) is a closest mammalian relative of PXR, which has also been proposed to function as a xenosensor. CAR is activated by some of the same ligands as PXR and regulates a subset of common genes. The sequence homology and functional similarity suggests that the CAR gene arose from a duplication of an ancestral PXR gene. Like other nuclear receptors, xenobiotic receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

 204-333 5.63e-08

Ligand binding domain of the progesterone receptor, a member of the nuclear hormone receptor; The ligand binding domain of the progesterone receptor (PR): PR is a member of the nuclear receptor superfamily of ligand dependent transcription factors, mediating the biological actions of progesterone. PR functions in a variety of biological processes including development of the mammary gland, regulating cell cycle progression, protein processing, and metabolism. When no binding hormone is present the carboxyl terminal inhibits transcription. Binding to a hormone induces a structural change that removes the inhibitory action. After progesterone binds to the receptor, PR forms a dimer and the complex enters the nucleus where it interacts with the hormone response element (HRE) in the promoters of progesterone responsive genes and alters their transcription. In addition, rapid actions of PR that occur independent of transcription, have also been observed in several tissues like brain, liver, mammary gland and spermatozoa. There are two natural PR isoforms called PR-A and PR-B. PR-B has an additional stretc h of 164 amino acids at the N terminus. The extra domain in PR-B performs activation functions by recruiting coactivators that could not be recruited by PR-A. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, PR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD). The LBD is not only involved in binding to progesterone, but also involved in coactivator binding and dimerization.

The ligand binding domain of vitamin D receptors, a member of the nuclear receptor superfamily; The ligand binding domain of vitamin D receptors (VDR): VDR is a member of the nuclear receptor (NR) superfamily that functions as classical endocrine receptors. VDR controls a wide range of biological activities including calcium metabolism, cell proliferation and differentiation, and immunomodulation. VDR is a high affinity receptor for the biologically most active Vitamin D metabolite, 1alpha,25-dihydroxyvitamin D3 (1alpha,25(OH)2D3). The binding of the ligand to the receptor induces a conformational change of the ligand binding domain (LBD) with consequent dissociation of corepressors. Upon ligand binding, VDR forms heterodimer with the retinoid X receptor (RXR) that binds to vitamin D response elements (VDREs), recruits coactivators. This leads to the expression of a large number of genes. Approximately 200 human genes are considered to be primary targets of VDR and even more genes are regulated indirectly. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, VDR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD).

Ligand binding domain of the glucocorticoid receptor, a member of the nuclear receptor superfamily; The ligand binding domain of the glucocorticoid receptor (GR): GR is a ligand-activated transcription factor belonging to the nuclear receptor superfamily. It binds with high affinity to cortisol and other glucocorticoids. GR is expressed in almost every cell in the body and regulates genes controlling a wide variety of processes including the development, metabolism, and immune response of the organism. In the absence of hormone, the glucocorticoid receptor (GR) is complexes with a variety of heat shock proteins in the cytosol. The binding of the glucocorticoids results in release of the heat shock proteins and transforms it to its active state. One mechanism of action of GR is by direct activation of gene transcription. The activated form of GR forms dimers, translocates into the nucleus, and binds to specific hormone responsive elements, activating gene transcription. GR can also function as a repressor of other gene transcription activators, such as NF-kappaB and AF-1 by directly binding to them, and bloc king the expression of their activated genes. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, GR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD). The LBD also functions for dimerization and chaperone protein association.

 204-382 8.93e-07

Ligand binding domain of the nuclear receptor androgen receptor, ligand activated transcription regulator; The ligand binding domain of the androgen receptor (AR): AR is a member of the nuclear receptor family. It is activated by binding either of the androgenic hormones, testosterone or dihydrotestosterone, which are responsible for male primary sexual characteristics and for secondary male characteristics, respectively. The primary mechanism of action of ARs is by direct regulation of gene transcription. The binding of an androgen results in a conformational change in the androgen receptor which causes its transport from the cytosol into the cell nucleus, and dimerization. The receptor dimer binds to a hormone response element of AR-regulated genes and modulates their expression. Another mode of action is independent of their interactions with DNA. The receptors interact directly with signal transduction proteins in the cytoplasm, causing rapid changes in cell function, such as ion transport. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, AR has a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a flexible hinge and a C-terminal ligand binding domain (LBD). The LBD is not only involved in binding to androgen, but also involved in binding of coactivator proteins and dimerization. A ligand dependent nuclear export signal is also present at the ligand binding domain.
