Translation initiation factor IF-2 mitochondrial is a protein that in humans is encoded by the MTIF2 gene.During the initiation of protein biosynthesis initiation factor-2 (IF-2) promotes the binding of the initiator tRNA to the small subunit of the ribosome in a GTP-dependent manner. Prokaryotic IF-2 is a single polypeptide while eukaryotic cytoplasmic IF-2 (eIF-2) is a trimeric protein.
