This antibody detects full-length calpain 2 as well as calpain 2 autoproteolytically cleaved at serine 20. This antibody does not detect recombinant calpain 1.\nSpecies Reactivity: Human, Mouse, Rat\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nPolyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the human sequence of calpain 2 (large subunit). Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nCalpain is a calcium-dependent thiol proteinase that is functionally active as a heterodimer composed of a small regulatory subunit and one of at least two large catalytic subunits (calpain 1 or calpain 2). , calpain 1 (mu-calpain) requires micromolar levels of calcium, while calpain 2 (M-calpain) requires millimolar levels of calcium for activation. The regulation of calpain is the subject of many current studies, which suggest that proteolytic activity is regulated post-transcriptionally by mechanisms such as calcium requirements, subcellular localization of the heterodimer, phosphorylation via the EGFR-Erk signaling cascade, endogenous inhibitors (calpastatin), and autoproteolytic cleavage (1). Calpastatin negatively regulates autoproteolytic cleavage of calpain 1 between Gly27 and Leu28 (2). Calpain influences cell migration by modifying rather than degrading its substrates responsible for cell adhesion and cytoskeletal arrangement. Control of calpain activity has caught the attention of drug development since limiting its activity could mute invasiveness of tumors or chronic inflammation (1).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCalcium-activated neutral proteinase 2; Calpain 2; calpain 2, (m\/II) large subunit; calpain 2, large [catalytic] subunit; calpain 2, large subunit; Calpain large polypeptide L2; Calpain M-type; Calpain-2; Calpain-2 catalytic subunit; Calpain-2 large subunit; calpain, large polypeptide L2; CAN2; CANP 2; CANP2; CANPL2; CANPml; CAPN2; FLJ39928; M-calpain; mCANP; Millimolar-calpain\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 80\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46797894582441,"sku":"2539S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2539s","provider":"Iright","version":"1.0","type":"link"}
