PFAM accession number:PF00472
Interpro abstract (IPR000352):

Peptide chain release factors (RFs) are required for the termination of protein biosynthesis [ (PUBMED:8821264) ]. At present two classes of RFs can be distinguished. Class I RFs bind to ribosomes that have encountered a stop codon at their decoding site and induce release of the nascent polypeptide. Class II RFs are GTP-binding proteins that interact with class I RFs and enhance class I RF activity. In prokaryotes there are two class I RFs that act in a codon specific manner [ (PUBMED:2215213) ]: RF-1(gene prfA) mediates UAA and UAG-dependent termination while RF-2 (gene prfB) mediates UAA and UGA-dependent termination. RF-1 and RF-2 are structurally and evolutionary related proteins which have been shown to be part of a larger family [ (PUBMED:1408743) ].

GO process:translational termination (GO:0006415)
GO function:translation release factor activity (GO:0003747)
