Eukaryotic translation initiation factor 4 gamma 3 is a protein that in humans is encoded by the EIF4G3 gene.^[5]^[6] The gene encodes a protein that functions in translation by aiding the assembly of the ribosome onto the messenger RNA template.^[7] 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.^[8]

Interactions[edit]

EIF4G3 has been shown to interact with PABPC1.^[9]
