cyclophilin_RING: cyclophilin-type peptidylprolyl cis- trans isomerases (cyclophilins) having a modified RING finger domain. This group includes the nuclear proteins, Human hCyP-60 and Caenorhabditis elegans MOG-6 which, compared to the archetypal cyclophilin Human cyclophilin A exhibit reduced peptidylprolyl cis- trans isomerase activity and lack a residue important for cyclophilin binding. Human hCyP-60 has been shown to physically interact with the proteinase inhibitor peptide eglin c and; C. elegans MOG-6 to physically interact with MEP-1, a nuclear zinc finger protein. MOG-6 has been shown to function in germline sex determination.

 38-110 2.97e-46

U-box domain, a modified RING finger, found in peptidyl-prolyl cis-trans isomerase-like 2 (PPIL2) and similar proteins; PPIL2 (EC 5.2.1.8), also known as PPIase, CYC4, cyclophilin-60 (Cyp60), cyclophilin-like protein Cyp-60, or Rotamase PPIL2, is a nuclear-specific cyclophilin which interacts with the proteinase inhibitor eglin c and regulates gene expression. PPIL2 belongs to the cyclophilin family of peptidylprolyl isomerases and catalyzes cis-trans isomerization of proline-peptide bonds, which is often a rate-limiting step in protein folding. It positively regulates beta-site amyloid precursor protein cleaving enzyme (BACE1) expression and beta-secretase activity. Moreover, PPIL2 plays an important role in the translocation of CD147 to the cell surface, and thus may present a novel target for therapeutic interventions in diseases where CD147 functions as a pathogenic factor in cancer, human immunodeficiency virus infection, or rheumatoid arthritis. PPIL2 contains an N-terminal RING-like U-box domain and a C-terminal cyclophilin (Cyp)-like chaperone domain.

 100-159 1.34e-09

RING finger (Really Interesting New Gene) domain and U-box domain superfamily; The RING finger is a specialized type of Zn-finger of 40 to 60 residues that binds two atoms of zinc. It is defined by the "cross-brace" motif that chelates zinc atoms by eight amino acid residues, typically Cys or His, arranged in a characteristic spacing. Canonical RING motifs have been categorized into two major subclasses, RING-HC (C3HC4-type) and RING-H2 (C3H2C3-type), according to their Cys/His content. There are also many variants of RING fingers: some have different Cys/His patterns while some lack a single Cys or His residue at typical Zn ligand positions (the fourth or eighth zinc ligand is prevalently exchanged for an Asp, which can indeed chelate Zn in a RING finger as well). C4C4-, C3HC3D-, C2H2C4-, and C3HC5-type RING fingers are closely related to RING-HC fingers. In contrast, C4HC3- (RING-CH alias RINGv), C3H3C2-, C3H2C2D-, C3DHC3-, and C4HC2H-type RING fingers are more closely related to RING-H2 fingers. However, not all RING finger-containing proteins display regular RING finger features, and the RING finger family has turned out to be multifarious. The degenerate RING fingers of the Siz/PIAS RING (SP-RING) family proteins and sporulation protein RMD5, are characterized by lacking the second, fifth, and sixth Zn2+ ion-coordinating residues. They bind only one Zn2+ ion. On the other hand, the RING fingers of the human APC11 and RBX1 proteins can bind a third Zn atom since they harbor four additional Zn ligands. U-box is a modified form of the RING finger domain that lacks metal chelating Cys and His residues. It resembles the cross-brace RING structure consisting of three beta-sheets and a single alpha-helix, which would be stabilized by salt bridges instead of chelated metal ions. U-box proteins are widely distributed among eukaryotic organisms and show a higher prevalence in plants than in other organisms. RING finger/U-box-containing proteins are a group of diverse proteins with a variety of cellular functions, including oncogenesis, development, viral replication, signal transduction, the cell cycle and apoptosis. Many of them are ubiquitin-protein ligases (E3s) that serve as scaffolds for binding to ubiquitin-conjugating enzymes (E2s, also referred to as ubiquitin carrier proteins or UBCs) in close proximity to substrate proteins, which enable efficient transfer of ubiquitin from E2 to the substrates.

Cyclophilin type peptidyl-prolyl cis-trans isomerase/CLD; The peptidyl-prolyl cis-trans isomerases, also known as cyclophilins, share this domain of about 109 amino acids. Cyclophilins have been found in all organizms studied so far and catalyze peptidyl-prolyl isomerization during which the peptide bond preceding proline (the peptidyl-prolyl bond) is stabilized in the cis conformation. Mammalian cyclophilin A (CypA) is a major cellular target for the immunosuppressive drug cyclosporin A (CsA). Other roles for cyclophilins may include chaperone and cell signalling function.

 100-159 1.34e-09

U-box domain 2, a modified RING finger, found in nitric oxide synthase-interacting protein (NOSIP) and similar proteins; NOSIP, also known as endothelial NO synthase (eNOS)-interacting protein, p33RUL, is an E3 ubiquitin-protein ligase implicated in the control of airway and vascular diameter, mucosal secretion, NO synthesis in ciliated epithelium, and, therefore, of mucociliary and bronchial function. The loss of NOSIP may cause holoprosencephaly and facial anomalies including cleft lip/palate, cyclopia and facial midline clefting. NOSIP interacts with neuronal nitric oxide synthase (nNOS) and eNOS by inhibiting nitric oxide (NO) production. It acts as a novel type of modulator that promotes translocation of eNOS from the plasma membrane to intracellular sites, thereby uncoupling eNOS from plasma membrane caveolae and inhibiting NO synthesis. NOSIP also interacts with protein phosphatase PP2A and mediates the monoubiquitination of the PP2A catalytic subunit. Thus, it is a critical modulator of brain and craniofacial development in mice and a candidate gene for holoprosencephaly in humans. Moreover, NOSIP associates with the erythropoietin (Epo) receptor (EpoR), mediates ubiquitination of EpoR, and plays an essential role in erythropoietin-induced proliferation. NOSIP contains an atypical N-terminal RING-like U-box domain that is split into two parts by an interjacent stretch of 104 amino acid residues, as well as a C-terminal RING-like U-box domain. This model corresponds to the second U-box domain.

cyclophilin: cyclophilin-type peptidylprolyl cis- trans isomerases. This family contains eukaryotic, bacterial and archeal proteins which exhibit a peptidylprolyl cis- trans isomerases activity (PPIase, Rotamase) and in addition bind the immunosuppressive drug cyclosporin (CsA). Immunosuppression in vertebrates is believed to be the result of the cyclophilin A-cyclosporin protein drug complex binding to and inhibiting the protein-phosphatase calcineurin. PPIase is an enzyme which accelerates protein folding by catalyzing the cis-trans isomerization of the peptide bonds preceding proline residues. Cyclophilins are a diverse family in terms of function and have been implicated in protein folding processes which depend on catalytic /chaperone-like activities. This group contains human cyclophilin 40, a co-chaperone of the hsp90 chaperone system; human cyclophilin A, a chaperone in the HIV-1 infectious process and; human cyclophilin H, a component of the U4/U6 snRNP, whose isomerization or chaperoning activities may play a role in RNA splicing.

Cyclophilin type peptidyl-prolyl cis-trans isomerase/CLD; The peptidyl-prolyl cis-trans isomerases, also known as cyclophilins, share this domain of about 109 amino acids. Cyclophilins have been found in all organizms studied so far and catalyze peptidyl-prolyl isomerization during which the peptide bond preceding proline (the peptidyl-prolyl bond) is stabilized in the cis conformation. Mammalian cyclophilin A (CypA) is a major cellular target for the immunosuppressive drug cyclosporin A (CsA). Other roles for cyclophilins may include chaperone and cell signalling function.

 38-110 2.97e-46

U-box domain, a modified RING finger, found in peptidyl-prolyl cis-trans isomerase-like 2 (PPIL2) and similar proteins; PPIL2 (EC 5.2.1.8), also known as PPIase, CYC4, cyclophilin-60 (Cyp60), cyclophilin-like protein Cyp-60, or Rotamase PPIL2, is a nuclear-specific cyclophilin which interacts with the proteinase inhibitor eglin c and regulates gene expression. PPIL2 belongs to the cyclophilin family of peptidylprolyl isomerases and catalyzes cis-trans isomerization of proline-peptide bonds, which is often a rate-limiting step in protein folding. It positively regulates beta-site amyloid precursor protein cleaving enzyme (BACE1) expression and beta-secretase activity. Moreover, PPIL2 plays an important role in the translocation of CD147 to the cell surface, and thus may present a novel target for therapeutic interventions in diseases where CD147 functions as a pathogenic factor in cancer, human immunodeficiency virus infection, or rheumatoid arthritis. PPIL2 contains an N-terminal RING-like U-box domain and a C-terminal cyclophilin (Cyp)-like chaperone domain.

This family represents the archetypal cystolic cyclophilin similar to human cyclophilins A, B and H. PPIase is an enzyme which accelerates protein folding by catalyzing the cis-trans isomerization of the peptide bonds preceding proline residues. These enzymes have been implicated in protein folding processes which depend on catalytic /chaperone-like activities. As cyclophilins, Human hCyP-A, human cyclophilin-B (hCyP-19), S. cerevisiae Cpr1 and C. elegans Cyp-3, are inhibited by the immunosuppressive drug cyclopsporin A (CsA). CsA binds to the PPIase active site. Cyp-3. S. cerevisiae Cpr1 interacts with the Rpd3 - Sin3 complex and in addition is a component of the Set3 complex. S. cerevisiae Cpr1 has also been shown to have a role in Zpr1p nuclear transport. Human cyclophilin H associates with the [U4/U6.U5] tri-snRNP particles of the splicesome.

 41-83 1.07e-11

U-box domain, a modified RING finger; The U-box protein family is a family of E3 enzymes that also includes the HECT family and the RING finger family. The E3 enzyme is ubiquitin-protein ligase that cooperates with a ubiquitin-activating enzyme (E1) and a ubiquitin-conjugating enzyme (E2), and plays a central role in determining the specificity of the ubiquitination system. It removes the ubiquitin molecule from the E2 enzyme and attaches it to the target substrate, forming a covalent bond between ubiquitin and the target. U-box proteins are characterized by the presence of a U-box domain of approximately 70 amino acids. The U-box is a modified form of the RING finger domain that lacks metal chelating cysteines and histidines. It resembles the cross-brace RING structure consisting of three beta-sheets and a single alpha-helix, which would be stabilized by salt bridges instead of chelated metal ions. U-box proteins are widely distributed among eukaryotic organisms and show a higher prevalence in plants than in other organisms.

 100-159 1.34e-09

U-box domain 2, a modified RING finger, found in nitric oxide synthase-interacting protein (NOSIP) and similar proteins; NOSIP, also known as endothelial NO synthase (eNOS)-interacting protein, p33RUL, is an E3 ubiquitin-protein ligase implicated in the control of airway and vascular diameter, mucosal secretion, NO synthesis in ciliated epithelium, and, therefore, of mucociliary and bronchial function. The loss of NOSIP may cause holoprosencephaly and facial anomalies including cleft lip/palate, cyclopia and facial midline clefting. NOSIP interacts with neuronal nitric oxide synthase (nNOS) and eNOS by inhibiting nitric oxide (NO) production. It acts as a novel type of modulator that promotes translocation of eNOS from the plasma membrane to intracellular sites, thereby uncoupling eNOS from plasma membrane caveolae and inhibiting NO synthesis. NOSIP also interacts with protein phosphatase PP2A and mediates the monoubiquitination of the PP2A catalytic subunit. Thus, it is a critical modulator of brain and craniofacial development in mice and a candidate gene for holoprosencephaly in humans. Moreover, NOSIP associates with the erythropoietin (Epo) receptor (EpoR), mediates ubiquitination of EpoR, and plays an essential role in erythropoietin-induced proliferation. NOSIP contains an atypical N-terminal RING-like U-box domain that is split into two parts by an interjacent stretch of 104 amino acid residues, as well as a C-terminal RING-like U-box domain. This model corresponds to the second U-box domain.

U-box domain, a modified RING finger, found in Arabidopsis plant U-box proteins (AtPUB) and similar proteins; The plant PUB proteins, also known as U-box domain-containing proteins, are much more numerous in Arabidopsis which has 62 in comparison with the typical 6 in most animals. The majority of AtPUBs in this subfamily are known as ARM domain-containing PUB proteins, containing a C-terminally-located, tandem ARM (armadillo) repeat protein-interaction region in addition to the U-box domain. They have been implicated in the regulation of cell death and defense. They also play important roles in other plant-specific pathways, such as controlling both self-incompatibility and pseudo-self-incompatibility, as well as acting in abiotic stress. A subgroup of ARM domain-containing PUB proteins harbors a plant-specific U-box N-terminal domain.
