Database IDHIV0000933
UniProt IDO43432
Primary gene name(s)EIF4G3
Synonym gene name(s)unknown
Protein nameEukaryotic translation initiation factor 4 gamma 3
Protein functionProbable component of the protein complex eIF4F, which is involved in the recognition of the mRNA cap, ATP-dependent unwinding of 5'-terminal secondary structure and recruitment of mRNA to the ribosome. Thought to be a functional homolog of EIF4G1. {ECO:0000269|PubMed:9418880}.
