Detection of Human eIF2 alpha by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line, K562 human chronic myelogenous leukemia cell line, and MCF-7 human breast cancer cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human eIF2a Monoclonal Antibody (Catalog # MAB3997) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for eIF2a at approximately 40 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: eIF2 alpha

Eukaryotic translation initiation factor 2 alpha subunit (eIF2 alpha ) is a subunit of the eIF2 protein, an important regulator of translation initiation. Phosphorylation of eIF2 alpha on Ser 52 increases the affinity of eIF2 alpha for eIF2B, a guanine nucleotide exchange factor needed for the recycling of eIF2-GDP to eIF2-GTP. Reduction of eIF2-GTP levels leads to the suppression of the overall rate of protein synthesis. Heme-regulated inhibitor (HRI), ER-resident protein kinase PERK, dsRNA activated protein kinase PKR, and the homologue of the S. cerevisiae protein kinase GCN2 are all eIF2 alpha kinases.
