ASK1 is activated in response to a variety of stress-related stimuli through distinct mechanisms and activates MKK4 and MKK3, which in turn activate JNK and p38 (3). Overexpression of ASK1 activates JNK and p38 and induces apoptosis in several cell types through signals involving the mitochondrial cell death pathway. Embryonic fibroblasts or primary neurons derived from ASK1-\/- mice are resistant to stress-induced JNK and p38 activation as well as cell death (4,5). Phosphorylation at Ser967 is essential for ASK1 association with 14-3-3 proteins and suppression of cell death (6). Oxidative stress induces dephosphorylation of Ser967 and phosphorylation of Thr845 in the activation loop of ASK1, both of which are correlated with ASK1 activity and ASK1-dependent apoptosis (7,8). Akt phosphorylates ASK1 at Ser83, which attenuates ASK1 activity and promotes cell survival (9). Phosphorylation at Ser967 of ASK1 leads to association of 14-3-3 and suppression of ASK1 kinase activity (6).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\napoptosis signal regulating kinase 1; apoptosis signal-regulating kinase 1; ASK-1; ASK1; M3K5; MAP\/ERK kinase kinase 5; MAP3K5; MAPK\/ERK kinase kinase 5; MAPKKK5; MEK kinase 5; MEKK 5; MEKK5; Mitogen-activated protein kinase kinase kinase 5; Mitogen-activated protein kinase kinase kinase 5 variant\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Transfected Only\nMW (kDa): 155\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799456010409,"sku":"3764S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3764s","provider":"Iright","version":"1.0","type":"link"}
