Phosphorylation of the alpha subunit of eukaryotic initiation factor 2 (eIF2alpha) is known to be an important translational control mechanism. Regulation of mammalian eIF2alpha activity is directly governed by specific phosphorylation on Serine 52. In mammalian cells, eIF2alpha is phosphorylated at Serine 52 by at least two kinases, the haem-controlled repressor and the interferon-inducible double stranded RNA-dependent protein kinase. This phosphorylation event results in an inhibition in the exchange of bound nucleotides and the recycling of eIF2alpha. In addition, phosphorylation of eIF2alpha blocks the GDP-GTP exchange activity of eIF2beta, resulting in the suppression of protein synthesis.Synonyms: EIF2-A, Eukaryotic translation initiation factor 2 subunit 1, Eukaryotic translation initiation factor 2 subunit alpha, eIF-2-alpha, eIF-2A, eIF-2alpha, eIF2 alpha
