RL   Submitted (AUG-2006) to the EMBL/GenBank/DDBJ databases.
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. {ECO:0000255|HAMAP-Rule:MF_00093}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00093}.
CC   -!- PTM: Methylated by PrmC. Methylation increases the termination
CC       efficiency of RF1. {ECO:0000255|HAMAP-Rule:MF_00093}.
CC   -!- SIMILARITY: Belongs to the prokaryotic/mitochondrial release factor
CC       family. {ECO:0000255|HAMAP-Rule:MF_00093}.
