 50-137 1.32e-58

RNA recognition motif (RRM)-like Smg4_UPF3 domain in up-frameshift suppressor 3 homolog B on chromosome X (Upf3B); This subgroup corresponds to the RRM-like Smg4_UPF3 domain in Upf3B, also termed regulator of nonsense transcripts 3B, or nonsense mRNA reducing factor 3B, a human ortholog of yeast Upf3p and Caenorhabditis elegans SMG-4. It derives from X-linked gene UPF3B and is required for nonsense-mediated mRNA decay (NMD) in human. Upf3B is a nucleocytoplasmic shuttling protein that associates selectively with spliced beta-globin mRNA in vivo. Like other Upf3 proteins, Upf3B contains nuclear import and export signals, and a conserved Smg4_UPF3 domain with some similarity to an RNA recognition motif (RRM), indicating that it may be an RNA binding protein.

 52-135 6.78e-37

RNA recognition motif (RRM)-like Smg4_UPF3 domain in yeast up-frameshift suppressor 3 (Upf3p), Caenorhabditis elegans SMG-4, their human orthologs Upf3A and Upf3B, and similar proteins; This subfamily corresponds to the RRM-like Smg4_UPF3 domain found in yeast up-frameshift suppressor 3 (Upf3p), Caenorhabditis elegans SMG-4, their human orthologs Upf3A and Upf3B, and similar proteins. Upf3p, also termed nonsense-mediated mRNA decay protein 3, or Sua6p, a surveillance factor encoded by UPF3 gene from Saccharomyces cerevisiae. It is required for nonsense-mediated mRNA decay (NMD) in yeast. Upf3p is primarily cytoplasmic but accumulates inside the nucleus. Its nuclear import is mediated by the Srp1p (importin-alpha)/beta heterodimer while its nuclear export is mediated by a leucine-rich nuclear export sequence (NES-A), but not the Crm1p exportin. C. elegans SMG-4 is a nuclear shuttling protein that shuttles between the cytoplasm and nucleus through nuclear import and export signals similar to that of the yeast Upf3p. It is regulated by phosphorylation. Human orthologs of yeast Upf3p and C. elegans SMG-4 include Upf3A and Upf3B, which derive from two genes, UPF3A and X-linked UPF3B, respectively. Both, Upf3A (Up-frameshift suppressor 3 homolog A, also termed regulator of nonsense transcripts 3A, or nonsense mRNA reducing factor 3A) and Upf3B (Up-frameshift suppressor 3 homolog B on chromosome X, also termed regulator of nonsense transcripts 3B, or nonsense mRNA reducing factor 3B), are nucleocytoplasmic shuttling proteins. They associate selectively with spliced beta-globin mRNA in vivo, and tethering of any human Upf protein to the 3'UTR of beta-globin mRNA prevents NMD. The function of the Upf proteins in identifying and targeting nonsense mRNAs for rapid decay is conserved among eukaryotes. Besides, all Upf proteins in this family contain a conserved Smg4_UPF3 domain with some similarity to an RNA recognition motif (RRM), indicating that they may be RNA binding proteins.

RNA recognition motif 3 (RRM3) found in Mei2-like proteins and terminal EAR1-like proteins; ...
 53-137 4.02e-04

RNA recognition motif 3 (RRM3) found in Mei2-like proteins and terminal EAR1-like proteins; This subfamily corresponds to the RRM3 of Mei2-like proteins from plant and fungi, terminal EAR1-like proteins from plant, and other eukaryotic homologs. Mei2-like proteins represent an ancient eukaryotic RNA-binding proteins family whose corresponding Mei2-like genes appear to have arisen early in eukaryote evolution, been lost from some lineages such as Saccharomyces cerevisiae and metazoans, and diversified in the plant lineage. The plant Mei2-like genes may function in cell fate specification during development, rather than as stimulators of meiosis. In the fission yeast Schizosaccharomyces pombe, the Mei2 protein is an essential component of the switch from mitotic to meiotic growth. S. pombe Mei2 stimulates meiosis in the nucleus upon binding a specific non-coding RNA. The terminal EAR1-like protein 1 and 2 (TEL1 and TEL2) are mainly found in land plants. They may play a role in the regulation of leaf initiation. All members in this family are putative RNA-binding proteins carrying three RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains). In addition to the RRMs, the terminal EAR1-like proteins also contain TEL characteristic motifs that allow sequence and putative functional discrimination between them and Mei2-like proteins.

 53-123 5.24e-04

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).
