Archaeal aIF2B interacts with eukaryotic translation initiation factors eIF2α and eIF2Bα: implications for aIF2B function and eIF2B regulation

Translation initiation is down-regulated in eukaryotes by phosphorylation of the α subunit of eIF2, which inhibits its guanine nucleotide exchange factor eIF2B. The N-terminal S1 domain of phosphorylated eIF2α interacts with a subcomplex of eIF2B formed by the three regulatory subunits, α/GCN3, β/GC...
