This domain is found in peptide chain release factors such as RF-1 and RF-2, and a number of smaller proteins of unknown function. This domain contains the peptidyl-tRNA hydrolase activity. The domain contains a highly conserved motif GGQ, where the glutamine is thought to coordinate the water that mediates the hydrolysis. Length = 114

In many but not all taxa, there is a conserved real translational frameshift at a TGA codon. RF-2 helps terminate translation at TGA codons and can therefore regulate its own production by readthrough when RF-2 is insufficient. There is a PFAM model called "RF-1" for the superfamily of RF-1, RF-2, mitochondrial, RF-H, etc [Protein synthesis, Translation factors]. Length = 364

Members of this protein family are bacterial proteins homologous to peptide chain release factors 1 (RF-1, product of the prfA gene), and 2 (RF-2, product of the prfB gene). The member from Escherichia coli K-12, designated prfH, appears to be a pseudogene. This class I release factor is always found as the downstream gene of a two-gene operon [Protein synthesis, Translation factors]. Length = 200

Members of this protein family are bacterial proteins homologous to peptide chain release factors 1 (RF-1, product of the prfA gene), and 2 (RF-2, product of the prfB gene). The member from Escherichia coli K-12, designated prfH, appears to be a pseudogene. This class I release factor is always found as the downstream gene of a two-gene operon.

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 []: 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 [].; GO: 0003747 translation release factor activity, 0006415 translational termination; PDB: 2JY9_A 1ZBT_A 1GQE_A 3F1G_X 3F1E_X 1RQ0_C 4DH9_Y 2JVA_A 1J26_A 3D5A_X ....
