Gene

EIF2S1

Species
Homo sapiens
Symbol
EIF2S1
Name
eukaryotic translation initiation factor 2 subunit alpha
Synonyms
  • EIF-2
  • eIF-2-alpha
Biotype
protein coding gene
Automated Description
Enables ribosome binding activity and translation initiation factor activity. Involved in several processes, including integrated stress response signaling; mitophagy; and regulation of translation in response to endoplasmic reticulum stress. Located in cytosol. Part of eukaryotic translation initiation factor 2 complex. Is active in mitochondrion. Implicated in Alzheimer's disease. Biomarker of Alzheimer's disease.
RGD Description
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 composed of 3 nonidentical subunits, the 36-kD EIF2-alpha subunit (EIF2S1), the 38-kD EIF2-beta subunit (EIF2S2; MIM 603908), and the 52-kD EIF2-gamma subunit (EIF2S3; MIM 300161). The rate of formation of the ternary complex is modulated by the phosphorylation state of EIF2-alpha (Ernst et al., 1987 [PubMed 2948954]).[supplied by OMIM, Feb 2010]
