Predicted to enable mRNA binding activity and translation initiation factor activity. Involved in mitotic cell cycle. Predicted to be located in cytoplasm. Predicted to be part of eukaryotic translation initiation factor 3 complex. Is expressed in several structures, including adult head; anterior endoderm; embryonic/larval midgut primordium; gut section; and larval muscle cell. Orthologous to human EIF3G (eukaryotic translation initiation factor 3 subunit G).
