RRMRNA recognition motif
|SMART accession number:||SM00360
|Interpro abstract (IPR000504):
||Many eukaryotic proteins that are known or supposed to bind single-stranded RNA contain one or more copies of a putative RNA-binding domain of about 90 amino acids. This is known as the eukaryotic putative RNA-binding region RNP-1 signature or RNA recognition motif (RRM). RRMs are found in a variety of RNA binding proteins, including heterogeneous nuclear ribonucleoproteins (hnRNPs), proteins implicated in regulation of alternative splicing, and protein components of small nuclear ribonucleoproteins (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. Two individual models were built which identify subtypes of this domain, but there is no functional difference between the subtypes.
