Western Blotting

Western blot analysis of extracts from HT29 (human) and AR42J (mouse) cells, untreated or thapsigargin-treated (300 nM, 30 min), using Phospho-eIF2alpha (Ser51) (119A11) Rabbit mAb (upper) or eIF2alpha Antibody #9722 (lower).
Western Blotting

Western blot analysis of extracts from HeLa and THP-1 cells untreated or phosphatase treated, using Phospho-eIF2alpha (Ser51) (119A11) Rabbit mAb.
IP

Western blot analysis of immunoprecipitates from PC12 cells, using Phospho-eIF2alpha (Ser51) (119A11) Rabbit mAb. Lane 1 is lysate control, lane 2 is the antibody alone as negative control and lane 3 is antibody immunocomplex of PC12 cells.

Phosphorylation of the eukaryotic initiation factor 2 (eIF2) α subunit is a well-documented mechanism to downregulate protein synthesis under a variety of stress conditions. eIF2 binds GTP and Met-tRNAi and transfers Met-tRNA to the 40S subunit to form the 43S preinitiation complex (1,2). eIF2 promotes a new round of translation initiation by exchanging GDP for GTP, a reaction catalyzed by eIF2B (1,2). Kinases that are activated by viral infection (PKR), endoplasmic reticulum stress (PERK/PEK), amino acid deprivation (GCN2), or heme deficiency (HRI) can phosphorylate the α subunit of eIF2 (3,4). This phosphorylation stabilizes the eIF2-GDP-eIF2B complex and inhibits the turnover of eIF2B. Induction of PKR by IFN-γ and TNF-α induces potent phosphorylation of eIF2α at Ser51 (5,6).
