Expression of caspase-4 has been observed in most tissues except brain, with highest levels in placenta, lung, spleen, and peripheral blood lymphocytes (PBL). Caspase-4 was originally found to contribute to Fas-mediated apoptosis (4). Several caspases (including caspase-4, caspase-5, and mouse caspase-11 and -12) are most closely related to caspase-1 and are capable of inducing apoptosis when overexpressed but are better characterized in the proteolytic activation of inflammatory cytokines (5). Caspase-4 associates with TRAF6 and is involved in the LPS inducible production of inflammatory cytokines IL-8 and MIP1 in THP-1 cells (6). While caspase-4 and mouse caspase-12 localize to the endoplasmic reticulum (ER) and may be activated by drugs that induce ER stress (7), at least one study suggests that caspase-4 and caspase-12 are not essential for ER stress-induced apoptosis (8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\napoptotic cysteine protease Mih1\/TX; CASP-4; CASP4; caspase 4; caspase 4, apoptosis-related cysteine peptidase; caspase 4, apoptosis-related cysteine protease; Caspase-4; Caspase-4 subunit 1; Caspase-4 subunit 2; Caspase4; ICE and Ced-3 homolog 2; ICE(rel)-II; ICE(rel)II; ICEREL-II; ICH-2; ICH2; Mih1; Mih1\/TX; Protease ICH-2; Protease TX; TX\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 22-25, 32-48\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799495528617,"sku":"42264S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-42264s","provider":"Iright","version":"1.0","type":"link"}
