Kinases activated by viral infection (PKR), endoplasmic reticulum stress (PERK\/PEK), amino acid deprivation (GCN2), and hemin deficiency (HRI) can phosphorylate the eIF2 alpha subunit (1,2). GCN2 is also required for UV light-induced translation inhibition, and phosphorylation of murine GCN2 at Thr898 is induced by both UV irradiation and by leucine deprivation (3). UV-induced activation of NF-κB also requires GCN2, which may act simply by preventing translation of IκB-alpha to replace pools that have been ubiquitinated and degraded (4). Interestingly, proteasome inhibitors (MG132 and ALLN) activate the GCN2\/eIF2alpha pathway, suggesting a pivotal role for this kinase in stress response and ubiquitin-mediated signaling (5). autophosphorylation of yeast GCN2 within its activation loop at Thr882 and Thr887 (Thr898 and Thr903 in mouse) has also been reported (6).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nE2AK4; eIF-2-alpha kinase GCN2; EIF2AK4; eukaryotic translation initiation factor 2 alpha kinase 4; Eukaryotic translation initiation factor 2-alpha kinase 4; GCN2; GCN2 eIF2alpha kinase; GCN2-like protein; general control nonderepressible 2; KIAA1338; PVOD2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 220\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800516645033,"sku":"70592S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-70592s","provider":"Iright","version":"1.0","type":"link"}
