EIF2alpha Colorimetric Cell-Based ELISA Kit

EIF-2-alpha; EIF-2A; EIF-2alpha; EIF2S1; Eukaryotic translation initiation factor 2 alpha subunit; Eukaryotic translation initiation factor 2 subunit 1; IF2A

Functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S pre-initiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2- GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B.
