InterPro : IPR003029

Name  Ribosomal protein S1, RNA-binding domain Short Name  Rbsml_prot_S1_RNA-bd_dom
Type  Domain Description  The S1 domain was originally identified in ribosomal protein S1 but is found in a large number of RNA-associated proteins. The structure of the S1 RNA-binding domain from the Escherichia colipolynucleotide phosphorylase has been determined using NMR methods and consists of a five-stranded antiparallel beta barrel. Conserved residues on one face of the barrel and adjacent loops form the putative RNA-binding site []. The structure of the S1 domain is very similar to that of cold shock proteins. This suggests that they may both be derived from an ancient nucleic acid-binding protein [].This entry does not include translation initiation factor IF-1 S1 domains.
