Accession MF_00072
Dates 1-JUN-2001 (Created)
9-DEC-2011 (Last updated, Version 27)
Data class Protein
Names Rel_fac_3



Identifier RF3
Protein name
RecName: Full=Peptide chain release factor 3;
Short=RF-3;
Gene name prfC
FUNCTION: Increases the formation of ribosomal termination complexes and stimulates activities of RF-1 and RF-2. It binds guanine nucleotides and has strong preference for UGA stop codons. It may interact directly with the ribosome. The stimulation of RF-1 and RF-2 is significantly reduced by GTP and GDP, but not by GMP (By similarity).
SUBCELLULAR LOCATION: Cytoplasm (By similarity).
SIMILARITY: Belongs to the GTP-binding elongation factor family. PrfC subfamily.
