Subsequently, eIF3 apparently assists eIF4 in recruiting mRNAs to the 43S complex. The eIF3 complex contains five conserved core subunits, and may contain several additional proteins; the non-core subunits are thought to mediate association of the complex with specific sets of mRNAs.",IDA GO:0006413,BP,"translational initiation","The process preceding formation of the peptide bond between the first two amino acids of a protein.
