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:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- PTM: Methylated by PrmC. Methylation increases the termination
CC       efficiency of RF2 (By similarity). {ECO:0000250}.
CC   -!- MISCELLANEOUS: The gene for this protein contains a UGA in-frame
CC       termination codon after Leu-25; a naturally occurring frameshift
CC       enables complete translation of RF-2. This provides a mechanism for the
CC       protein to regulate its own production.
CC   -!- SIMILARITY: Belongs to the prokaryotic/mitochondrial release factor
CC       family. {ECO:0000305}.
