Gene Information

human ... EIF2S1(1965)

General description

EIF2S1 (eukaryotic translation initiation factor 2 subunit α) is a heterotrimeric protein and a regulatory subunit of eIF2 . eIF2 has three general subunits- α, βand γ . eIF2α is located on human chromosome 14q23 .

Immunogen

The antiserum was produced against synthesized peptide derived from human eIF2 alpha around the phosphorylation site of Ser51.

Immunogen Range: 21-70

Application

Anti-phospho-eIF2 α(pSer51) antibody has been used in western blotting and immunohistochemistry.

Biochem/physiol Actions

EIF2S1 (eukaryotic translation initiation factor 2 subunit α) acts as a modulator in apoptosis signaling pathway . During endoplasmic reticulum stress, eIF2α plays a major role in signaling pathways in the development of tumor .
