Background and References September 30, 2021 2 https://www.prosci-inc.com/eif2s1-antibody-57-063.html 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 BACKGROUND: nonidentical subunits, the 36-kD EIF2-alpha subunit (EIF2S1), the 38-kD EIF2-beta subunit (EIF2S2; MIM 603908), and the 52-kD 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]). REFERENCES: 1) Shiota, M., et al. Int. J.
