Gene Gene information from NCBI Gene database.
Entrez ID 1965
Gene name Eukaryotic translation initiation factor 2 subunit alpha
Gene symbol EIF2S1
Synonyms (NCBI Gene)
EIF-2EIF-2AEIF-2alphaEIF2EIF2A
Chromosome 14
Chromosome location 14q23.3
Summary The translation initiation factor EIF2 catalyzes the first regulated step of protein synthesis initiation, promoting the binding of the initiator tRNA to 40S ribosomal subunits. Binding occurs as a ternary complex of methionyl-tRNA, EIF2, and GTP. EIF2 is

Protein name Eukaryotic translation initiation factor 2 subunit 1 (Eukaryotic translation initiation factor 2 subunit alpha) (eIF-2-alpha) (eIF-2A) (eIF-2alpha) (eIF2-alpha)
Protein function Member of the eIF2 complex that functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA (PubMed:16289705, PubMed:38340717). This complex binds to a 40S ribosomal subunit, followed by mRNA bindin
