Description: | - |
Interpro abstract (IPR014720): | In contrast to other RNA-binding domains, the about 65 amino acids long dsRBD domain [ (PUBMED:1438302) (PUBMED:8036511) (PUBMED:7972084) ] has been found in a number of proteins that specifically recognise double-stranded RNAs. The dsRBD domain is also known as DSRM (Double-Stranded RNA-binding Motif). dsRBD proteins are mainly involved in posttranscriptional gene regulation, for example by preventing the expression of proteins or by mediating RNAs localization. This domain is also found in RNA editing proteins. Interaction of the dsRBD with RNA is unlikely to involve the recognition of specific sequences [ (PUBMED:1357546) (PUBMED:7527340) (PUBMED:8127710) ]. Nevertheless, multiple dsRBDs may be able to act in combination to recognise the secondary structure of specific RNAs (i.e. Staufen) [ (PUBMED:1438302) ]. NMR analysis of the third dsRBD of Drosophila Staufen have revealed an alpha-beta-beta-beta-alpha structure [ (PUBMED:7628456) ]. |

Escherichia coli ribonucleases (RNases) HII, III, II, PH and D have been used to characterise new and known viral, bacterial, archaeal and eucaryotic sequences similar to these endo- (HII and III) and exoribonucleases (II, PH and D). Statistical models, hidden Markov models (HMMs), were created for the RNase HII, III, II and PH and D families as well as a double-stranded RNA binding domain present in RNase III. Results suggest that the RNase D family, which includes Werner syndrome protein and the 100 kDa antigenic component of the human polymyositis scleroderma (PMSCL) autoantigen, is a 3'-->5' exoribonuclease structurally and functionally related to the 3'-->5' exodeoxyribonuclease domain of DNA polymerases. Polynucleotide phosphorylases and the RNase PH family, which includes the 75 kDa PMSCL autoantigen, possess a common domain suggesting similar structures and mechanisms of action for these 3'-->5' phosphorolytic enzymes. Examination of HMM-generated multiple sequences alignments for each family suggest amino acids that may be important for their structure, substrate binding and/or catalysis.

Translation of hunchback(mat) (hb[mat]) mRNA must be repressed in the posterior of the pre-blastoderm Drosophila embryo to permit formation of abdominal segments. This translational repression requires two copies of the Nanos Response Element (NRE), a 16-nt sequence in the hb[mat] 3' untranslated region. Translational repression also requires the action of two proteins: Pumilio (PUM), a sequence-specific RNA-binding protein; and Nanos, a protein that determines the location of repression. Binding of PUM to the NRE is thought to target hb(mat) mRNA for repression. Here, we show the RNA-binding domain of PUM to be an evolutionarily conserved, 334-amino acid region at the carboxy-terminus of the approximately 158-kDa PUM protein. This contiguous region of PUM retains the RNA-binding specificity of full-length PUM protein. Proteins with sequences homologous to the PUM RNA-binding domain are found in animals, plants, and fungi. The high degree of sequence conservation of the PUM RNA-binding domain in other far-flung species suggests that the domain is an ancient protein motif, and we show that conservation of sequence reflects conservation of function: that is, the homologous region from a human protein binds RNA with sequence specificity related to but distinct from Drosophila PUM.

In eukaryotic cells, a multitude of RNA-binding proteins play key roles in the posttranscriptional regulation of gene expression. Characterization of these proteins has led to the identification of several RNA-binding motifs, and recent experiments have begun to illustrate how several of them bind RNA. The significance of these interactions is reflected in the recent discoveries that several human and other vertebrate genetic disorders are caused by aberrant expression of RNA-binding proteins. The major RNA-binding motifs are described and examples of how they may function are given.

We have identified a double-stranded (ds)RNA-binding domain in each of two proteins: the product of the Drosophila gene staufen, which is required for the localization of maternal mRNAs, and a protein of unknown function, Xlrbpa, from Xenopus. The amino acid sequences of the binding domains are similar to each other and to additional domains in each protein. Database searches identified similar domains in several other proteins known or thought to bind dsRNA, including human dsRNA-activated inhibitor (DAI), human trans-activating region (TAR)-binding protein, and Escherichia coli RNase III. By analyzing in detail one domain in staufen and one in Xlrbpa, we delimited the minimal region that binds dsRNA. On the basis of the binding studies and computer analysis, we have derived a consensus sequence that defines a 65- to 68-amino acid dsRNA-binding domain.
