This antibody detects the full-length (inactive) cathepsin A precursor in addition to the processed (active) light chain. This antibody detects a 75 kDa protein of unknown identity in some cell lines by western blotting. Non-specific nuclear staining was observed in testis by immunohistochemistry.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human cathepsin A protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nCathepsin A, also known as lysosomal protective protein for beta-galactosidase (PPGB), functions as both a serine protease and a critical enzyme for stabilizing β-galactosidase and neuraminidase (1,2). Similar to other cathepsin family members, cathepsin A is synthesized as an inactive 54 kDa precursor, then cleaved into catalytically active large (32 kDa) and small (20 kDa) subunits that form a disulfide-linked heterodimer after excision of a linker peptide (1-3). Cathepsin A degradation targets include endothelin (4), LAMP2 (5), and angiotensin I (6). gene mutations result in protein misfolding and lysosomal galactosialidosis, as neuraminidase and β-galactosidase activity depend on direct association with cathepsin A (7,8). Cathepsin A overexpression in heart causes excess degradation of superoxide dismutase (SOD), increasing oxidative stress, inflammation, and remodeling of the extracellular matrix (ECM) (9). High expression of cathepsin A has been reported and associated with metastasis in melanocytic tumors, colorectal cancer, hepatocellular carcinoma, and lung adenocarcinoma (10-13).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nbeta-galactosidase 2; beta-galactosidase protective protein; Carboxypeptidase C; Carboxypeptidase L; carboxypeptidase Y-like kininase; carboxypeptidase-L; Cathepsin A; CTSA; deamidase; GLB2; GSL; lysosomal carboxypeptidase A; Lysosomal protective protein; Lysosomal protective protein 20 kDa chain; Lysosomal protective protein 32 kDa chain; NGBE; PPCA; PPGB; Protective protein cathepsin A; Protective protein for beta-galactosidase; urinary kininase\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 54, 20\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799849816233,"sku":"67452T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-67452t","provider":"Iright","version":"1.0","type":"link"}
