Tight Binding of the Phosphorylated α Subunit of Initiation Factor 2 (eIF2α) to the Regulatory Subunits of Guanine Nucleotide Exchange Factor eIF2B Is Required for Inhibition of Translation Initiation

Translation initiation factor 2 (eIF2) is a heterotrimeric protein that transfers methionyl-initiator tRNA(Met) to the small ribosomal subunit in a ternary complex with GTP. The eIF2 phosphorylated on serine 51 of its α subunit [eIF2(αP)] acts as competitive inhibitor of its guanine nucleotide excha...
