CC   -!- FUNCTION: Peptide chain release factor 1 directs the termination of
CC       translation in response to the peptide chain termination codons UAG and
CC       UAA (Probable). {ECO:0000305|PubMed:16377566,
CC       ECO:0000305|PubMed:9258437}.
CC   -!- SUBUNIT: Interacts with the ribosome (PubMed:16377566).
CC       {ECO:0000269|PubMed:16377566}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- PTM: Methylated by PrmC. Methylation increases the termination
CC       efficiency of RF1 (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the prokaryotic/mitochondrial release factor
CC       family. {ECO:0000305}.
