CID (CTD-Interacting Domain) of Splicing factor arginine serine rich 15; Splicing factor arginine serine rich 15 (SFRS15) is also called CTD-binding SR-like protein RA4 or SR-related and CTD-associated factor 4 (SCAF4). It may act to physically and functionally link transcription and pre-mRNA processing. SFRS15/SCAF4 contains a CTD-interacting domain (CID) at the amino terminus and a Ser/Arg-rich domain followed by an RNA recognition motif. CID binds tightly to the carboxy-terminal domain (CTD) of RNA polymerase (Pol) II (RNAP II). During transcription, RNAP II synthesizes eukaryotic messenger RNA. Transcription is coupled to RNA processing through the CTD, which consists of up to 52 repeats of the sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. CID contains eight alpha-helices in a right-handed superhelical arrangement, which closely resembles that of the VHS domains and ARM (Armadillo) repeat proteins, except for its two amino-terminal helices. : Pssm-ID: 340802 Cd Length: 131 Bit Score: 281.08 E-value: 2.53e-88

RNA recognition motif (RRM) found in SR-related and CTD-associated factor 4 (SCAF4) and similar proteins; The CD corresponds to the RRM of SCAF4 (also termed splicing factor, arginine/serine-rich 15 or SFR15, or CTD-binding SR-like protein RA4) that belongs to a new class of SCAFs (SR-like CTD-associated factors). Although its biological function remains unclear, SCAF4 shows high sequence similarity to SCAF8 that interacts specifically with a highly serine-phosphorylated form of the carboxy-terminal domain (CTD) of the largest subunit of RNA polymerase II (pol II) and may play a direct role in coupling with both, transcription and pre-mRNA processing, processes. SCAF4 and SCAF8 both contain a conserved N-terminal CTD-interacting domain (CID), an atypical RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), and serine/arginine-rich motifs. : Pssm-ID: 409894 [Multi-domain] Cd Length: 81 Bit Score: 187.56 E-value: 9.30e-56

RNA recognition motif. (a.k.a. RRM, RBD, or RNP domain); The RRM motif is probably diagnostic of an RNA binding protein. RRMs are found in a variety of RNA binding proteins, including various hnRNP proteins, proteins implicated in regulation of alternative splicing, and protein components of snRNPs. The motif also appears in a few single stranded DNA binding proteins. The RRM structure consists of four strands and two helices arranged in an alpha/beta sandwich, with a third helix present during RNA binding in some cases The C-terminal beta strand (4th strand) and final helix are hard to align and have been omitted in the SEED alignment The LA proteins have an N terminal rrm which is included in the seed. There is a second region towards the C terminus that has some features characteriztic of a rrm but does not appear to have the important structural core of a rrm. The LA proteins are one of the main autoantigens in Systemic lupus erythematosus (SLE), an autoimmune disease. Pssm-ID: 425453 [Multi-domain] Cd Length: 70 Bit Score: 51.46 E-value: 3.77e-08

N-terminal domain of Kruppel-like factor (KLF) 1, KLF2, KLF4, and similar proteins; Kruppel/Krueppel-like transcription factors (KLFs) belong to a family of proteins called the Specificity Protein (SP)/KLF family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. Members of the KLF family can act as activators or repressors of transcription depending on cell and promoter context. KLFs regulate various cellular functions, such as proliferation, differentiation, and apoptosis, as well as the development and homeostasis of several types of tissue. In addition to the C-terminal DNA-binding domain, each KLF also has a unique N-terminal activation/repression domain that confers specifity and allows it to bind specifically to a certain partner, leading to distinct activities in vivo. This model represents the related N-terminal domains of KLF1, KLF2, KLF4, and similar proteins. Pssm-ID: 409230 [Multi-domain] Cd Length: 194 Bit Score: 38.81 E-value: 8.13e-03

CID (CTD-Interacting Domain) of Nrd1 and similar proteins; This subfamily includes Saccharomyces cerevisiae protein Nrd1, Schizosaccharomyces pombe Rpb7-binding protein Seb1, and similar proteins. Nrd1 cooperates with Nab3 and Sen1, also called the Nrd1-Nab3-Sen1 (NNS) complex, to terminate the transcription by RNA polymerase (Pol) II (RNAPII) of many noncoding RNAs (ncRNAs), including small nuclear RNAs (snRNAs), small nucleolar RNAs (snoRNAs), and cryptic unstable transcripts (CUTs). Schizosaccharomyces pombe Seb1 does not function in an NNS-like termination pathway but promotes polyadenylation site selection of coding and noncoding genes. It cotranscriptionally controls alternative polyadenylation. CID binds tightly to the carboxy-terminal domain (CTD) of RNAP II. Nrd1 CID preferentially interacts with CTD phosphorylated at Ser5. During transcription, RNAP II synthesizes eukaryotic messenger RNA.

CID (CTD-Interacting Domain) of Pcf11; Pcf11 is conserved across eukaryotes. The best studied protein is Saccharomyces cerevisiae Pcf11, also called protein 1 of CF I, an essential subunit of the cleavage factor IA (CFIA) complex which is required for polyadenylation-dependent pre-mRNA 3'-end processing and RNA polymerase (Pol) II (RNAP II) transcription termination. Human Pcf11, also referred to as pre-mRNA cleavage complex 2 protein Pcf11, has been shown to enhance degradation of RNAP II-associated nascent RNA and transcriptional termination. The family also includes plant PCFS4 (Pcf11-similar-4 protein or Polyadenylation and cleavage factor homolog 4) and Caenorhabditis elegans Polyadenylation and cleavage factor homolog 11. CID binds tightly to the carboxy-terminal domain (CTD) of RNAP II. Pcf11 CID preferentially interacts with CTD phosphorylated at Ser2. During transcription, RNAP II synthesizes eukaryotic messenger RNA. Transcription is coupled to RNA processing through the CTD, which consists of up to 52 repeats of the sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. CID contains eight alpha-helices in a right-handed superhelical arrangement, which closely resembles that of the VHS domains and ARM (Armadillo) repeat proteins, except for its two amino-terminal helices.

RNA recognition motif (RRM) superfamily; RRM, also known as RBD (RNA binding domain) or RNP (ribonucleoprotein domain), is a highly abundant domain in eukaryotes found in proteins involved in post-transcriptional gene expression processes including mRNA and rRNA processing, RNA export, and RNA stability. This domain is 90 amino acids in length and consists of a four-stranded beta-sheet packed against two alpha-helices. RRM usually interacts with ssRNA, but is also known to interact with ssDNA as well as proteins. RRM binds a variable number of nucleotides, ranging from two to eight. The active site includes three aromatic side-chains located within the conserved RNP1 and RNP2 motifs of the domain. The RRM domain is found in a variety heterogeneous nuclear ribonucleoproteins (hnRNPs), proteins implicated in regulation of alternative splicing, and protein components of small nuclear ribonucleoproteins (snRNPs).

CELF, also termed BRUNOL (Bruno-like) proteins, is a family of structurally related RNA-binding proteins involved in regulation of pre-mRNA splicing in the nucleus, and control of mRNA translation and deadenylation in the cytoplasm. The family contains six members: CELF-1 (also known as BRUNOL-2, CUG-BP1, NAPOR, EDEN-BP), CELF-2 (also known as BRUNOL-3, ETR-3, CUG-BP2, NAPOR-2), CELF-3 (also known as BRUNOL-1, TNRC4, ETR-1, CAGH4, ER DA4), CELF-4 (BRUNOL-4), CELF-5 (BRUNOL-5) and CELF-6 (BRUNOL-6). They all contain three highly conserved RNA recognition motifs (RRMs), also known as RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains): two consecutive RRMs (RRM1 and RRM2) situated in the N-terminal region followed by a linker region and the third RRM (RRM3) close to the C-terminus of the protein. The low sequence conservation of the linker region is highly suggestive of a large variety in the co-factors that associate with the various CELF family members. Based on both, sequence similarity and function, the CELF family can be divided into two subfamilies, the first containing CELFs 1 and 2, and the second containing CELFs 3, 4, 5, and 6. The different CELF proteins may act through different sites on at least some substrates. Furthermore, CELF proteins may interact with each other in varying combinations to influence alternative splicing in different contexts. This subfamily also includes plant flowering time control protein FCA that functions in the posttranscriptional regulation of transcripts involved in the flowering process. FCA contains two RRMs, and a WW protein interaction domain. Pssm-ID: 409796 [Multi-domain] Cd Length: 77 Bit Score: 48.77 E-value: 3.34e-07

TIA-1 and TIAR share high sequence similarity. They are expressed in a wide variety of cell types. TIA-1 can be phosphorylated by a serine/threonine kinase that is activated during Fas-mediated apoptosis.TIAR is mainly localized in the nucleus of hematopoietic and nonhematopoietic cells.

RNA recognition motif (RRM) found in U1 small nuclear ribonucleoprotein 70 kDa (U1-70K) and similar proteins; This subfamily corresponds to the RRM of U1-70K, also termed snRNP70, a key component of the U1 snRNP complex, which is one of the key factors facilitating the splicing of pre-mRNA via interaction at the 5' splice site, and is involved in regulation of polyadenylation of some viral and cellular genes, enhancing or inhibiting efficient poly(A) site usage. U1-70K plays an essential role in targeting the U1 snRNP to the 5' splice site through protein-protein interactions with regulatory RNA-binding splicing factors, such as the RS protein ASF/SF2. Moreover, U1-70K protein can specifically bind to stem-loop I of the U1 small nuclear RNA (U1 snRNA) contained in the U1 snRNP complex. It also mediates the binding of U1C, another U1-specific protein, to the U1 snRNP complex. U1-70K contains a conserved RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), followed by an adjacent glycine-rich region at the N-terminal half, and two serine/arginine-rich (SR) domains at the C-terminal half. The RRM is responsible for the binding of stem-loop I of U1 snRNA molecule. Additionally, the most prominent immunodominant region that can be recognized by auto-antibodies from autoimmune patients may be located within the RRM. The SR domains are involved in protein-protein interaction with SR proteins that mediate 5' splice site recognition. For instance, the first SR domain is necessary and sufficient for ASF/SF2 Binding. The family also includes Drosophila U1-70K that is an essential splicing factor required for viability in flies, but its SR domain is dispensable. The yeast U1-70k doesn't contain easily recognizable SR domains and shows low sequence similarity in the RRM region with other U1-70k proteins and therefore not included in this family. The RRM domain is dispensable for yeast U1-70K function. Pssm-ID: 409682 [Multi-domain] Cd Length: 91 Bit Score: 46.46 E-value: 3.81e-06

CELF-3, expressed in brain and testis only, is also known as bruno-like protein 1 (BRUNOL-1), or CAG repeat protein 4, or CUG-BP- and ETR-3-like factor 3, or embryonic lethal abnormal vision (ELAV)-type RNA-binding protein 1 (ETR-1), or expanded repeat domain protein CAG/CTG 4, or trinucleotide repeat-containing gene 4 protein (TNRC4). It plays an important role in the pathogenesis of tauopathies. CELF-3 contains three highly conserved RNA recognition motifs (RRMs), also known as RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains): two consecutive RRMs (RRM1 and RRM2) situated in the N-terminal region followed by a linker region and the third RRM (RRM3) close to the C-terminus of the protein. The effect of CELF-3 on tau splicing is mediated mainly by the RNA-binding activity of RRM2. The divergent linker region might mediate the interaction of CELF-3 with other proteins regulating its activity or involved in target recognition. CELF-4, being highly expressed throughout the brain and in glandular tissues, moderately expressed in heart, skeletal muscle, and liver, is also known as bruno-like protein 4 (BRUNOL-4), or CUG-BP- and ETR-3-like factor 4. Like CELF-3, CELF-4 also contain three highly conserved RRMs. The splicing activation or repression activity of CELF-4 on some specific substrates is mediated by its RRM1/RRM2. On the other hand, both RRM1 and RRM2 of CELF-4 can activate cardiac troponin T (cTNT) exon 5 inclusion. CELF-5, expressed in brain, is also known as bruno-like protein 5 (BRUNOL-5), or CUG-BP- and ETR-3-like factor 5. Although its biological role remains unclear, CELF-5 shares same domain architecture with CELF-3. CELF-6, being strongly expressed in kidney, brain, and testis, is also known as bruno-like protein 6 (BRUNOL-6), or CUG-BP- and ETR-3-like factor 6. It activates exon inclusion of a cardiac troponin T minigene in transient transfection assays in a muscle-specific splicing enhancer (MSE)-dependent manner and can activate inclusion via multiple copies of a single element, MSE2. CELF-6 also promotes skipping of exon 11 of insulin receptor, a known target of CELF activity that is expressed in kidney. In addition to three highly conserved RRMs, CELF-6 also possesses numerous potential phosphorylation sites, a potential nuclear localization signal (NLS) at the C terminus, and an alanine-rich region within the divergent linker region.

High molecular weight glutenin subunit; Members of this family include high molecular weight subunits of glutenin. This group of gluten proteins is thought to be largely responsible for the elastic properties of gluten, and hence, doughs. Indeed, glutenin high molecular weight subunits are classified as elastomeric proteins, because the glutenin network can withstand significant deformations without breaking, and return to the original conformation when the stress is removed. Elastomeric proteins differ considerably in amino acid sequence, but they are all polymers whose subunits consist of elastomeric domains, composed of repeated motifs, and non-elastic domains that mediate cross-linking between the subunits. The elastomeric domain motifs are all rich in glycine residues in addition to other hydrophobic residues. High molecular weight glutenin subunits have an extensive central elastomeric domain, flanked by two terminal non-elastic domains that form disulphide cross-links. The central elastomeric domain is characterized by the following three repeated motifs: PGQGQQ, GYYPTS[P/L]QQ, GQQ. It possesses overlapping beta-turns within and between the repeated motifs, and assumes a regular helical secondary structure with a diameter of approx. 1.9 nm and a pitch of approx. 1.5 nm.

CID (CTD-Interacting Domain) of Regulation of nuclear pre-mRNA domain-containing protein 1A; Regulation of nuclear pre-mRNA domain-containing protein 1A (RPRD1A) is also called Cyclin-dependent kinase inhibitor 2B-related protein or p15INK4B-related protein (P15RS). RPRD1A is a CID (CTD-Interacting Domain) containing protein that co-purifies with RNA polymerase (Pol) II (RNAP II) and three other RNAP II-associated proteins, RPAP2, GRINL1A and RECQL5, but not with the Mediator complex. CID binds tightly to the carboxy-terminal domain (CTD) of RNAP II. During transcription, RNAP II synthesizes eukaryotic messenger RNA. Transcription is coupled to RNA processing through the CTD, which consists of up to 52 repeats of the sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. RPRD1A form homodimers and heterodimers with RPRD1B through their coiled-coil domains. Both RPRD1A and RPRD1B associate directly with RPAP2 phosphatase and serve as CTD scaffolds to coordinate the dephosphorylation of phospho-S5 by RPAP2. CID contains eight alpha-helices in a right-handed superhelical arrangement, which closely resembles that of the VHS domains and ARM (Armadillo) repeat proteins, except for its two amino-terminal helices.

RNA recognition motif 1 (RRM1) found in the Hu proteins family, Drosophila sex-lethal (SXL), and similar proteins; This subfamily corresponds to the RRM1 of Hu proteins and SXL. The Hu proteins family represents a group of RNA-binding proteins involved in diverse biological processes. Since the Hu proteins share high homology with the Drosophila embryonic lethal abnormal vision (ELAV) protein, the Hu family is sometimes referred to as the ELAV family. Drosophila ELAV is exclusively expressed in neurons and is required for the correct differentiation and survival of neurons in flies. The neuronal members of the Hu family include Hu-antigen B (HuB or ELAV-2 or Hel-N1), Hu-antigen C (HuC or ELAV-3 or PLE21), and Hu-antigen D (HuD or ELAV-4), which play important roles in neuronal differentiation, plasticity and memory. HuB is also expressed in gonads. Hu-antigen R (HuR or ELAV-1 or HuA) is ubiquitously expressed Hu family member. It has a variety of biological functions mostly related to the regulation of cellular response to DNA damage and other types of stress. Hu proteins perform their cytoplasmic and nuclear molecular functions by coordinately regulating functionally related mRNAs. In the cytoplasm, Hu proteins recognize and bind to AU-rich RNA elements (AREs) in the 3' untranslated regions (UTRs) of certain target mRNAs, such as GAP-43, vascular epithelial growth factor (VEGF), the glucose transporter GLUT1, eotaxin and c-fos, and stabilize those ARE-containing mRNAs. They also bind and regulate the translation of some target mRNAs, such as neurofilament M, GLUT1, and p27. In the nucleus, Hu proteins function as regulators of polyadenylation and alternative splicing. Each Hu protein contains three RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains). RRM1 and RRM2 may cooperate in binding to an ARE. RRM3 may help to maintain the stability of the RNA-protein complex, and might also bind to poly(A) tails or be involved in protein-protein interactions. This family also includes the sex-lethal protein (SXL) from Drosophila melanogaster. SXL governs sexual differentiation and X chromosome dosage compensation in flies. It induces female-specific alternative splicing of the transformer (tra) pre-mRNA by binding to the tra uridine-rich polypyrimidine tract at the non-sex-specific 3' splice site during the sex-determination process. SXL binds to its own pre-mRNA and promotes female-specific alternative splicing. It contains an N-terminal Gly/Asn-rich domain that may be responsible for the protein-protein interaction, and tandem RRMs that show high preference to bind single-stranded, uridine-rich target RNA transcripts.

CELF-3, expressed in brain and testis only, is also known as bruno-like protein 1 (BRUNOL-1), or CAG repeat protein 4, or CUG-BP- and ETR-3-like factor 3, or embryonic lethal abnormal vision (ELAV)-type RNA-binding protein 1 (ETR-1), or expanded repeat domain protein CAG/CTG 4, or trinucleotide repeat-containing gene 4 protein (TNRC4). It plays an important role in the pathogenesis of tauopathies. CELF-3 contains three highly conserved RNA recognition motifs (RRMs), also known as RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains): two consecutive RRMs (RRM1 and RRM2) situated in the N-terminal region followed by a linker region and the third RRM (RRM3) close to the C-terminus of the protein.The effect of CELF-3 on tau splicing is mediated mainly by the RNA-binding activity of RRM2. The divergent linker region might mediate the interaction of CELF-3 with other proteins regulating its activity or involved in target recognition. CELF-4, highly expressed throughout the brain and in glandular tissues, moderately expressed in heart, skeletal muscle, and liver, is also known as bruno-like protein 4 (BRUNOL-4), or CUG-BP- and ETR-3-like factor 4. Like CELF-3, CELF-4 also contain three highly conserved RRMs. The splicing activation or repression activity of CELF-4 on some specific substrates is mediated by its RRM1/RRM2. On the other hand, both RRM1 and RRM2 of CELF-4 can activate cardiac troponin T (cTNT) exon 5 inclusion.

It activates exon inclusion of a cardiac troponin T minigene in transient transfection assays in an muscle-specific splicing enhancer (MSE)-dependent manner and can activate inclusion via multiple copies of a single element, MSE2. CELF-6 also promotes skipping of exon 11 of insulin receptor, a known target of CELF activity that is expressed in kidney. In additiona to three highly conserved RRMs, CELF-6 also possesses numerous potential phosphorylation sites, a potential nuclear localization signal (NLS) at the C terminus, and an alanine-rich region within the divergent linker region.

The family represents type I polyadenylate-binding proteins (PABPs), including polyadenylate-binding protein 1 (PABP-1 or PABPC1), polyadenylate-binding protein 3 (PABP-3 or PABPC3), polyadenylate-binding protein 4 (PABP-4 or APP-1 or iPABP), polyadenylate-binding protein 5 (PABP-5 or PABPC5), polyadenylate-binding protein 1-like (PABP-1-like or PABPC1L), polyadenylate-binding protein 1-like 2 (PABPC1L2 or RBM32), polyadenylate-binding protein 4-like (PABP-4-like or PABPC4L), yeast polyadenylate-binding protein, cytoplasmic and nuclear (PABP or ACBP-67), and similar proteins. PABP-1 is a ubiquitously expressed multifunctional protein that may play a role in 3' end formation of mRNA, translation initiation, mRNA stabilization, protection of poly(A) from nuclease activity, mRNA deadenylation, inhibition of mRNA decapping, and mRNP maturation. Although PABP-1 is thought to be a cytoplasmic protein, it is also found in the nucleus. PABP-1 may be involved in nucleocytoplasmic trafficking and utilization of mRNP particles. PABP-1 contains four copies of RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), a less well conserved linker region, and a proline-rich C-terminal conserved domain (CTD). PABP-3 is a testis-specific poly(A)-binding protein specifically expressed in round spermatids. It is mainly found in mammalian and may play an important role in the testis-specific regulation of mRNA homeostasis. PABP-3 shows significant sequence similarity to PABP-1. However, it binds to poly(A) with a lower affinity than PABP-1. Moreover, PABP-1 possesses an A-rich sequence in its 5'-UTR and allows binding of PABP and blockage of translation of its own mRNA. In contrast, PABP-3 lacks the A-rich sequence in its 5'-UTR. PABP-4 is an inducible poly(A)-binding protein (iPABP) that is primarily localized to the cytoplasm. It shows significant sequence similarity to PABP-1 as well. The RNA binding properties of PABP-1 and PABP-4 appear to be identical. PABP-5 is encoded by PABPC5 gene within the X-specific subinterval, and expressed in fetal brain and in a range of adult tissues in mammals, such as ovary and testis. It may play an important role in germ cell development. Moreover, unlike other PABPs, PABP-5 contains only four RRMs, but lacks both the linker region and the CTD. PABP-1-like and PABP-1-like 2 are the orthologs of PABP-1. PABP-4-like is the ortholog of PABP-5. Their cellular functions remain unclear. The family also includes yeast PABP, a conserved poly(A) binding protein containing poly(A) tails that can be attached to the 3'-ends of mRNAs. The yeast PABP and its homologs may play important roles in the initiation of translation and in mRNA decay. Like vertebrate PABP-1, the yeast PABP contains four RRMs, a linker region, and a proline-rich CTD as well. The first two RRMs are mainly responsible for specific binding to poly(A). The proline-rich region may be involved in protein-protein interactions. Pssm-ID: 409812 [Multi-domain] Cd Length: 80 Bit Score: 39.15 E-value: 1.09e-03

High molecular weight glutenin subunit; Members of this family include high molecular weight subunits of glutenin. This group of gluten proteins is thought to be largely responsible for the elastic properties of gluten, and hence, doughs. Indeed, glutenin high molecular weight subunits are classified as elastomeric proteins, because the glutenin network can withstand significant deformations without breaking, and return to the original conformation when the stress is removed. Elastomeric proteins differ considerably in amino acid sequence, but they are all polymers whose subunits consist of elastomeric domains, composed of repeated motifs, and non-elastic domains that mediate cross-linking between the subunits. The elastomeric domain motifs are all rich in glycine residues in addition to other hydrophobic residues. High molecular weight glutenin subunits have an extensive central elastomeric domain, flanked by two terminal non-elastic domains that form disulphide cross-links. The central elastomeric domain is characterized by the following three repeated motifs: PGQGQQ, GYYPTS[P/L]QQ, GQQ. It possesses overlapping beta-turns within and between the repeated motifs, and assumes a regular helical secondary structure with a diameter of approx. 1.9 nm and a pitch of approx. 1.5 nm.

RNA recognition motif (RRM) found in yeast pre-mRNA-splicing factor Cwc2 and similar proteins; This subfamily corresponds to the RRM of yeast protein Cwc2, also termed Complexed with CEF1 protein 2, or PRP19-associated complex protein 40 (Ntc40), or synthetic lethal with CLF1 protein 3, one of the components of the Prp19-associated complex [nineteen complex (NTC)] that can bind to RNA. NTC is composed of the scaffold protein Prp19 and a number of associated splicing factors, and plays a crucial role in intron removal during premature mRNA splicing in eukaryotes. Cwc2 functions as an RNA-binding protein that can bind both small nuclear RNAs (snRNAs) and pre-mRNA in vitro. It interacts directly with the U6 snRNA to link the NTC to the spliceosome during pre-mRNA splicing. In the N-terminal half, Cwc2 contains a CCCH-type zinc finger (ZnF domain), a RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), and an intervening loop, also termed RNA-binding loop or RB loop, between ZnF and RRM, all of which are necessary and sufficient for RNA binding. The ZnF is also responsible for mediating protein-protein interaction. The C-terminal flexible region of Cwc2 interacts with the WD40 domain of Prp19.

It is involved in the regulation of mRNA splicing probably via its complex formation with RNA-binding protein with a serine-rich domain (RNPS1), a pre-mRNA-splicing factor. SART3 has also been identified as a nuclear Tat-interacting protein that regulates Tat transactivation activity through direct interaction and functions as an important cellular factor for HIV-1 gene expression and viral replication. In addition, SART3 is required for U6 snRNP targeting to Cajal bodies. It binds specifically and directly to the U6 snRNA, interacts transiently with the U6 and U4/U6 snRNPs, and promotes the reassembly of U4/U6 snRNPs after splicing in vitro. SART3 contains an N-terminal half-a-tetratricopeptide repeat (HAT)-rich domain, a nuclearlocalization signal (NLS) domain, and two C-terminal RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains).

CID (CTD-Interacting Domain) of Regulation of nuclear pre-mRNA domain-containing protein 1B; Regulation of nuclear pre-mRNA domain-containing protein 1B (RPRD1B) is also called Cell cycle-related and expression-elevated protein in tumor (CREPT). RPRD1B is a CID (CTD-Interacting Domain) containing protein that co-purifies with RNA polymerase (Pol) II (RNAP II) and three other RNAP II-associated proteins, RPAP2, GRINL1A and RECQL5, but not with the Mediator complex. CID binds tightly to the carboxy-terminal domain (CTD) of RNAP II. During transcription, RNAP II synthesizes eukaryotic messenger RNA. Transcription is coupled to RNA processing through the CTD, which consists of up to 52 repeats of the sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. RPRD1B form homodimers and heterodimers with RPRD1A through their coiled-coil domains. Both RPRD1A and RPRD1B associate directly with RPAP2 phosphatase and serve as CTD scaffolds to coordinate the dephosphorylation of phospho-S5 by RPAP2. RPRD1B is highly expressed during tumorigenesis and in endometrial cancer, has been shown to promote tumor growth by accelerating the cell cycle. CID contains eight alpha-helices in a right-handed superhelical arrangement, which closely resembles that of the VHS domains and ARM (Armadillo) repeat proteins, except for its two amino-terminal helices.

THOC4 is an mRNA transporter protein with a well conserved RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain). It is involved in RNA transportation from the nucleus, and was initially identified as a transcription coactivator of LEF-1 and AML-1 for the TCRalpha enhancer function. In addition, THOC4 specifically binds to rhesus (RH) promoter in erythroid, and might be a novel transcription cofactor for erythroid-specific genes. SKAR shows high sequence homology with THOC4 and possesses one RRM as well. SKAR is widely expressed and localizes to the nucleus. It may be a critical player in the function of S6K1 in cell and organism growth control by binding the activated, hyperphosphorylated form of S6K1 but not S6K2. Furthermore, SKAR functions as a protein partner of the p50 subunit of DNA polymerase delta. In addition, SKAR may have particular importance in pancreatic beta cell size determination and insulin secretion. Pssm-ID: 409852 [Multi-domain] Cd Length: 75 Bit Score: 37.94 E-value: 2.62e-03

Atrophin-1 family; Atrophin-1 is the protein product of the dentatorubral-pallidoluysian atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive neurodegenerative disorder. It is caused by the expansion of a CAG repeat in the DRPLA gene on chromosome 12p. This results in an extended polyglutamine region in atrophin-1, that is thought to confer toxicity to the protein, possibly through altering its interactions with other proteins. The expansion of a CAG repeat is also the underlying defect in six other neurodegenerative disorders, including Huntington's disease. One interaction of expanded polyglutamine repeats that is thought to be pathogenic is that with the short glutamine repeat in the transcriptional coactivator CREB binding protein, CBP. This interaction draws CBP away from its usual nuclear location to the expanded polyglutamine repeat protein aggregates that are characteriztic of the polyglutamine neurodegenerative disorders. This interferes with CBP-mediated transcription and causes cytotoxicity. Pssm-ID: 460830 [Multi-domain] Cd Length: 991 Bit Score: 42.06 E-value: 2.81e-03

RNA recognition motif (RRM) found in serine/arginine-rich splicing factor SRSF10, SRSF12 and similar proteins; This subfamily corresponds to the RRM of SRSF10 and SRSF12. SRSF10, also termed 40 kDa SR-repressor protein (SRrp40), or FUS-interacting serine-arginine-rich protein 1 (FUSIP1), or splicing factor SRp38, or splicing factor, arginine/serine-rich 13A (SFRS13A), or TLS-associated protein with Ser-Arg repeats (TASR). It is a serine-arginine (SR) protein that acts as a potent and general splicing repressor when dephosphorylated. It mediates global inhibition of splicing both in M phase of the cell cycle and in response to heat shock. SRSF10 emerges as a modulator of cholesterol homeostasis through the regulation of low-density lipoprotein receptor (LDLR) splicing efficiency. It also regulates cardiac-specific alternative splicing of triadin pre-mRNA and is required for proper Ca2+ handling during embryonic heart development. In contrast, the phosphorylated SRSF10 functions as a sequence-specific splicing activator in the presence of a nuclear cofactor. It activates distal alternative 5' splice site of adenovirus E1A pre-mRNA in vivo. Moreover, SRSF10 strengthens pre-mRNA recognition by U1 and U2 snRNPs. SRSF10 localizes to the nuclear speckles and can shuttle between nucleus and cytoplasm. SRSF12, also termed 35 kDa SR repressor protein (SRrp35), or splicing factor, arginine/serine-rich 13B (SFRS13B), or splicing factor, arginine/serine-rich 19 (SFRS19), is a serine/arginine (SR) protein-like alternative splicing regulator that antagonizes authentic SR proteins in the modulation of alternative 5' splice site choice. For instance, it activates distal alternative 5' splice site of the adenovirus E1A pre-mRNA in vivo. Both, SRSF10 and SRSF12, contain a single N-terminal RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), followed by a C-terminal RS domain rich in serine-arginine dipeptides.

CELF-1 is strongly expressed in all adult and fetal tissues tested. The human CELF-1 is a nuclear and cytoplasmic RNA-binding protein that regulates multiple aspects of nuclear and cytoplasmic mRNA processing, with implications for onset of type 1 myotonic dystrophy (DM1), a neuromuscular disease associated with an unstable CUG triplet expansion in the 3'-UTR (3'-untranslated region) of the DMPK (myotonic dystrophy protein kinase) gene; it preferentially targets UGU-rich mRNA elements. It has been shown to bind to a Bruno response element, a cis-element involved in translational control of oskar mRNA in Drosophila, and share sequence similarity to Bruno, the Drosophila protein that mediates this process. The Xenopus homolog embryo deadenylation element-binding protein (EDEN-BP) mediates sequence-specific deadenylation of Eg5 mRNA. It binds specifically to the EDEN motif in the 3'-untranslated regions of maternal mRNAs and targets these mRNAs for deadenylation and translational repression. CELF-1 contain three highly conserved RNA recognition motifs (RRMs), also known as RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains): two consecutive RRMs (RRM1 and RRM2) situated in the N-terminal region followed by a linker region and the third RRM (RRM3) close to the C-terminus of the protein. The two N-terminal RRMs of EDEN-BP are necessary for the interaction with EDEN as well as a part of the linker region (between RRM2 and RRM3). Oligomerization of EDEN-BP is required for specific mRNA deadenylation and binding. CELF-2 is expressed in all tissues at some level, but highest in brain, heart, and thymus. It has been implicated in the regulation of nuclear and cytoplasmic RNA processing events, including alternative splicing, RNA editing, stability and translation. CELF-2 shares high sequence identity with CELF-1, but shows different binding specificity; it binds preferentially to sequences with UG repeats and UGUU motifs. It has been shown to bind to a Bruno response element, a cis-element involved in translational control of oskar mRNA in Drosophila, and share sequence similarity to Bruno, the Drosophila protein that mediates this process. It also binds to the 3'-UTR of cyclooxygenase-2 messages, affecting both translation and mRNA stability, and binds to apoB mRNA, regulating its C to U editing. CELF-2 also contains three highly conserved RRMs. It binds to RNA via the first two RRMs, which are also important for localization in the cytoplasm. The splicing activation or repression activity of CELF-2 on some specific substrates is mediated by RRM1/RRM2. Both, RRM1 and RRM2 of CELF-2, can activate cardiac troponin T (cTNT) exon 5 inclusion. In addition, CELF-2 possesses a typical arginine and lysine-rich nuclear localization signal (NLS) in the C-terminus, within RRM3. This subgroup also includes Drosophila melanogaster Bruno protein, which plays a central role in regulation of Oskar (Osk) expression in flies. It mediates repression by binding to regulatory Bruno response elements (BREs) in the Osk mRNA 3' UTR. The full-length Bruno protein contains three RRMs, two located in the N-terminal half of the protein and the third near the C-terminus, separated by a linker region.

N-terminal domain of Kruppel-like factor (KLF) 1, KLF2, KLF4, and similar proteins; Kruppel/Krueppel-like transcription factors (KLFs) belong to a family of proteins called the Specificity Protein (SP)/KLF family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. Members of the KLF family can act as activators or repressors of transcription depending on cell and promoter context. KLFs regulate various cellular functions, such as proliferation, differentiation, and apoptosis, as well as the development and homeostasis of several types of tissue. In addition to the C-terminal DNA-binding domain, each KLF also has a unique N-terminal activation/repression domain that confers specifity and allows it to bind specifically to a certain partner, leading to distinct activities in vivo. This model represents the related N-terminal domains of KLF1, KLF2, KLF4, and similar proteins. Pssm-ID: 409230 [Multi-domain] Cd Length: 194 Bit Score: 38.81 E-value: 8.13e-03
