Homologous Superfamily

RNA-binding S4 domain superfamily (IPR036986)

Short name: S4_RNA-bd_sf

Overlapping entries


The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast protein containing a pseudouridine synthetase and a deaminase domain, bacterial tyrosyl-tRNA synthetases, and a number of uncharacterised, small proteins that may be involved in translation regulation [PMID: 10093218]. The S4 domain probably mediates binding to RNA [PMID: 9707415].
