CC -!- FUNCTION: Peptide chain release factor 2 directs the termination of
CC translation in response to the peptide chain termination codons UGA and
CC UAA. {ECO:0000255|HAMAP-Rule:MF_00094}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00094}.
CC -!- PTM: Methylated by PrmC. Methylation increases the termination
CC efficiency of RF2. {ECO:0000255|HAMAP-Rule:MF_00094}.
CC -!- SIMILARITY: Belongs to the prokaryotic/mitochondrial release factor
CC family. {ECO:0000255|HAMAP-Rule:MF_00094}.
