During the initiation of protein biosynthesis, initiationfactor-2 (IF-2) promotes the binding of the initiator tRNA to thesmall subunit of the ribosome in a GTP-dependent manner.Prokaryotic IF-2 is a single polypeptide, while eukaryoticcytoplasmic IF-2 (eIF-2) is a trimeric protein. Bovine livermitochondria contain IF-2(mt), an 85-kD monomeric protein that isequivalent to prokaryotic IF-2. The predicted 727-amino acid humanprotein contains a 29-amino acid presequence. Human IF-2(mt) shares32 to 38% amino acid sequence identity with yeast IF-2(mt) andseveral prokaryotic IF-2s, with the greatest degree of conservationin the G domains of the proteins. Two transcript variants encodingthe same protein have been found for this gene. [provided byRefSeq].
