機能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 40 S subunits in a codon-dependent manner, whereas the eIF-2 complex binds methionyl-tRNAi to 40 S subunits in a GTP-dependent manner. May act by impiging the expression of specific proteins.
組織特異性Widely expressed. Expressed at higher level in pancreas, heart, brain and placenta.
配列類似性Belongs to the WD repeat EIF2A family. Contains 3 WD repeats.
