CC   -!- FUNCTION: Increases the formation of ribosomal termination complexes
CC       and stimulates activities of RF-1 and RF-2. It binds guanine
CC       nucleotides and has strong preference for UGA stop codons. It may
CC       interact directly with the ribosome. The stimulation of RF-1 and RF-2
CC       is significantly reduced by GTP and GDP, but not by GMP.
CC       {ECO:0000255|HAMAP-Rule:MF_00072}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00072}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC       superfamily. Classic translation factor GTPase family. PrfC subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00072}.
