 54-171 2.46e-73

K homology (KH) RNA-binding domain, type I; KH binds single-stranded RNA or DNA. It is found in a wide variety of proteins including ribosomal proteins, transcription factors and post-transcriptional modifiers of mRNA. There are two different KH domains that belong to different protein folds, but they share a single KH motif. The KH motif is folded into a beta alpha alpha beta unit. In addition to the core, type II KH domains (e.g. ribosomal protein S3) include an N-terminal extension and type I KH domains (e.g. hnRNP K) contain a C-terminal extension. Some KH-I superfamily members contain a divergent KH domain that lacks the RNA-binding GXXG motif. Some others have a mutated GXXG motif which may or may not have nucleic acid binding ability.

Qua1 domain; This domain, approximately 40 residues in length, is mainly found in KH-domain containing, RNA-binding, signal transduction-associated protein 1 from yeast to human. It forms a homodimer composed of a perpendicular interaction of two helical hairpins, and the Qua1 domain is sufficient for homodimerization which is required for the regulation of alternative splicing.

 56-157 6.85e-66

type I K homology (KH) RNA-binding domain found in the KH domain-containing, RNA-binding, signal transduction-associated protein (KHDRBS) family; The KHDRBS family includes three members, KHDRBS1-3. KHDRBS1, also called GAP-associated tyrosine phosphoprotein p62, or Src-associated in mitosis 68 kDa protein, or Sam68, or p21 Ras GTPase-activating protein-associated p62, or p68, is an RNA-binding protein that plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon inclusion. It binds to RNA containing 5'-[AU]UAA-3' as a bipartite motif spaced by more than 15 nucleotides. It also binds poly(A). KHDRBS1 acts as a putative regulator of mRNA stability and/or translation rates and mediates mRNA nuclear export. It is recruited and tyrosine phosphorylated by several receptor systems, for example the T-cell, leptin and insulin receptors. KHDRBS2, also called Sam68-like mammalian protein 1, or SLM-1, is an RNA-binding protein that plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon inclusion. It binds both poly(A) and poly(U) homopolymers. KHDRBS2 may function as an adapter protein for Src kinases during mitosis. KHDRBS3, also called RNA-binding protein T-Star, or Sam68-like mammalian protein 2, or SLM-2, or Sam68-like phosphotyrosine protein, is an RNA-binding protein that plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon inclusion. It binds optimally to RNA containing 5'-[AU]UAA-3' as a bipartite motif spaced by more than 15 nucleotides. It also binds poly(A). KHDRBS3 may play a role as a negative regulator of cell growth.

 59-161 7.35e-42

type I K homology (KH) RNA-binding domain found in protein quaking (Hqk) family; The Hqk family includes Hqk and protein held out wings (how) found in Drosophila. Hqk, also called HqkI, is an RNA-binding protein that plays a central role in myelinization. It binds to the 5'-NACUAAY-N(1,20)-UAAY-3' RNA core sequence and regulates target mRNA stability. It acts by regulating pre-mRNA splicing, mRNA export and protein translation. Hqk is a regulator of oligodendrocyte differentiation and maturation in the brain that may play a role in myelin and oligodendrocyte dysfunction in schizophrenia. How, also called KH domain protein KH93F, or protein muscle-specific, or protein Struthio, or protein wings held out (who), or Quaking-related 93F (qkr93F), is an RNA-binding protein involved in the control of muscular and cardiac activity. It is required for integrin-mediated cell-adhesion in wing blade. It plays essential roles during embryogenesis, in late stages of somatic muscle development, for myotube migration and during metamorphosis for muscle reorganization.

type I K homology (KH) RNA-binding domain found in protein quaking (Hqk) and similar proteins; Hqk, also called HqkI, is an RNA-binding protein that plays a central role in myelinization. It binds to the 5'-NACUAAY-N(1,20)-UAAY-3' RNA core sequence and regulates target mRNA stability. It acts by regulating pre-mRNA splicing, mRNA export and protein translation. Hqk is a regulator of oligodendrocyte differentiation and maturation in the brain that may play a role in myelin and oligodendrocyte dysfunction in schizophrenia.

K homology (KH) RNA-binding domain, type I; KH binds single-stranded RNA or DNA. It is found in a wide variety of proteins including ribosomal proteins, transcription factors and post-transcriptional modifiers of mRNA. There are two different KH domains that belong to different protein folds, but they share a single KH motif. The KH motif is folded into a beta alpha alpha beta unit. In addition to the core, type II KH domains (e.g. ribosomal protein S3) include an N-terminal extension and type I KH domains (e.g. hnRNP K) contain a C-terminal extension. Some KH-I superfamily members contain a divergent KH domain that lacks the RNA-binding GXXG motif. Some others have a mutated GXXG motif which may or may not have nucleic acid binding ability.

It acts as an RNA-binding factor that may recruit target transcripts to cytoplasmic protein-RNA complexes (mRNPs). It also modulates the rate and location at which target transcripts encounter the translational apparatus and shields them from endonuclease attacks or microRNA-mediated degradation. IGF2BP3 binds to the 3'-UTR of CD44 mRNA and stabilizes it, hence promotes cell adhesion and invadopodia formation in cancer cells. It also binds to beta-actin/ACTB and MYC transcripts. IGF2BP3 can form homooligomers and heterooligomers with IGF2BP1 and IGF2BP2 in an RNA-dependent manner. IGF2BP3 contains four K-homology (KH) RNA-binding domains which are important in RNA binding and are known to be involved in RNA synthesis and metabolism. The model corresponds to the second one.

 62-101 9.65e-03

third type I K homology (KH) RNA-binding domain found in vigilin and similar proteins; Vigilin, also called high density lipoprotein-binding protein, or HDL-binding protein, is a ubiquitous and highly conserved RNA-binding protein that shuttles between nucleus and cytoplasm presumably in contact with RNA molecules. It may be involved in chromosome partitioning at mitosis, facilitating translation and tRNA transport, and control of mRNA metabolism, including estrogen-mediated stabilization of vitellogenin mRNA. Vigilin is up-regulated by cholesterol loading of cells and functions to protect cells from over-accumulation of cholesterol. It may play a role in cell sterol metabolism. Disruption of human vigilin impairs chromosome condensation and segregation. Vigilin has a unique structure of 14-15 consecutively arranged, but non-identical K-homology (KH) domains which apparently mediate RNA-protein binding. The model corresponds to the third one.
