The translation initiation factor EIF2 catalyzes the first regulated step of protein synthesis initiation, promoting the binding of the initiator tRNA to 40S ribosomal subunits.
Binding occurs as a ternary complex of methionyl-tRNA, EIF2, and GTP.
EIF2 is composed of 3 nonidentical subunits, the 36kD EIF2-alpha subunit (EIF2S1), the 38kD EIF2-beta subunit (EIF2S2; MIM 603908), and the 52kD EIF2-gamma subunit (EIF2S3; MIM 300161).
The rate of formation of the ternary complex is modulated by the phosphorylation state of EIF2-alpha (Ernst et al., 1987 [PubMed 2948954]).
