EIF2A
Function
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.
Sequence Similarities
Belongs to the WD repeat EIF2A family.
Tissue Specificity
Widely expressed. Expressed at higher level in pancreas, heart, brain and placenta.
Alternative names
CDA02, MSTP004, MSTP089, EIF2A, Eukaryotic translation initiation factor 2A, eIF-2A, 65 kDa eukaryotic translation initiation factor 2A
