| Specificity/Sensitivity | Phospho-eIF2α (Ser51) (D9G8) XP® Rabbit mAb detects endogenous eIF2α only when phosphorylated at Ser51. The antibody does not recognize elF2α phosphorylated at other sites. Human eIF2alpha residue Ser52 historically has been referenced as Ser51. |
| Species Reactivity | Human, Mouse, Rat, Monkey, D. melanogaster |
| Source/Purification | Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser51 of human eIF2α. |
| Background | 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). |
