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:0000256|HAMAP-Rule:MF_00094}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00094}.
CC -!- PTM: Methylated by PrmC. Methylation increases the termination
CC efficiency of RF2. {ECO:0000256|HAMAP-Rule:MF_00094}.
CC -!- SIMILARITY: Belongs to the prokaryotic/mitochondrial release factor
CC family. {ECO:0000256|ARBA:ARBA00010835, ECO:0000256|HAMAP-
CC Rule:MF_00094}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:PXA65060.1}.
