In molecular biology translation initiation factor IF-3 (gene infC) is one of the three factors required for the initiation of protein biosynthesis in bacteria. IF-3 is thought to function as a fidelity factor during the assembly of the ternary initiation complex which consists of the 30S ribosomal subunit the initiator tRNA and the messenger RNA. IF-3 is a basic protein that binds to the 30S ribosomal subunit.
