EIF2A
Functions in the early steps of protein synthesis of a small number of specific mRNAs. Acts by directing the binding of methionyl-tRNAi to 40S ribosomal subunits. In contrast to the eIF-2 complex, it binds methionyl-tRNAi to 40S subunits in a codon-dependent manner, whereas the eIF-2 complex binds methionyl-tRNAi to 40S subunits in a GTP-dependent manner. Belongs to the WD repeat EIF2A family. Widely expressed. Expressed at higher level in pancreas, heart, brain and placenta. 4 alternatively spliced human isoforms have been reported.
