Abstract excerpt

Eukaryotic translation initiation factor 2B (eIF2B) is the guanine nucleotide exchange factor (GEF) for eukaryotic translation initiation factor 2, which stimulates formation of the eIF2-GTP-Met-tRNA(i)(Met) ternary complex (TC) in a manner inhibited by phosphorylated eIF2 [eIF2(αP)]. While eIF2B contains five subunits, the ε/Gcd6 subunit is sufficient for GEF activity in vitro. The δ/Gcd2 and β/Gcd7 subunits...
