EIF4G3

Template:PBB Eukaryotic translation initiation factor 4 gamma 3 is a protein that in humans is encoded by the EIF4G3 gene.^[1]^[2] The gene encodes a protein that functions in translation by aiding the assembly of the ribosome onto the messenger RNA template.^[3] Confusingly, this protein is usually referred to as eIF4GII, as although EIF4G3 is the third gene that is similar to eukaryotic translation initiation factor 4 gamma, the second isoform EIF4G2 is not an active translation initiation factor.^[4]

Interactions

EIF4G3 has been shown to interact with PABPC1.^[5]
