eIF3 consists of a core of five non-identical subunits (eIF3a, eIF3b, eIF3c, eIF3i and eIF3g in yeast) and up to six additional subunits in mammals (eIF3d, eIF3e, eIF3f, eIF3h, eIFj and eIF3k). binding to and stabilization of ternary complex, binding to the 40S ribosome, facilitating the binding of mRNA to the 40S ribosome, and promoting dissociation of 40S and 60S ribosomal subunits eukaryotic initiation factor 3 eIF
