Protein Name: Eukaryotic translation initiation factor 2 subunit 3
|
UniprotKB/SwissProt ID: IF2G_HUMAN (P41091)
Gene Name: EIF2S3
Synonyms: EIF2G
Organism: Homo sapiens (Human).
Function: eIF-2 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 preinitiation 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.
