ER stress increases the activity of PERK, which then phosphorylates eIF2α to promote reduced translation. Research studies have demonstrated that PERK-deficient mice have defects in pancreatic β cells several weeks after birth, suggesting a role for PERK-mediated translational control in protecting secretory cells from ER stress (4). PERK activation during ER stress correlates with autophosphorylation of its cytoplasmic kinase domain (1-3). Phosphorylation of PERK at Thr980 serves as a marker for its activation status.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDKFZp781H1925; E2AK3; EIF2AK3; eukaryotic translation initiation factor 2 alpha kinase 3; Eukaryotic translation initiation factor 2-alpha kinase 3; heme-regulated EIF2-alpha kinase; HRI; HsPEK; Pancreatic eIF2-alpha kinase; PEK; PERK; PRKR-like endoplasmic reticulum kinase; truncated eukaryotic translation initiation factor 2 alpha kinase 3; WRS\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 140\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800969924777,"sku":"3192T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3192t","provider":"Iright","version":"1.0","type":"link"}
