Protein Name:
Eukaryotic translation initiation factor 2 subunit alpha
|
UniprotKB/SwissProt ID: Q9FE78 (Q9FE78)
Gene Name:
EIF2A
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: 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 eIF2B
