Carbonic Anhydrase II (CA2) Antibody – Rabbit Polyclonal

CA2: Essential for bone resorption and osteoclast differentiation. Reversible hydration of carbon dioxide. Can hydrates cyanamide to urea. Involved in the regulation of fluid secretion into the anterior chamber of the eye. Interacts with SLC4A4. Interaction with SLC4A7 regulates SLC4A7 transporter activity. Activated by X-ray, histamine, L-adrenaline, L- and D-phenylalanine, L- and D-histidine, L-His-OMe and beta-Ala- His (carnosine). Competitively inhibited by saccharin, thioxolone, coumarins, 667-coumate, celecoxib (Celebrex), valdecoxib (Bextra), SC-125, SC-560, diclofenac, acetate, azide, bromide, sulfonamide derivatives such as acetazolamide (AZA), methazolamide (MZA), ethoxzolamide (EZA), dichlorophenamide (DCP), brinzolamide, dansylamide, thiabendazole-5-sulfonamide, trifluoromethane sulfonamide and N-hydroxysulfamide, fructose-based sugar sulfamate RWJ-37497, and Foscarnet (phosphonoformate trisodium salt). Repressed strongly by hydrogen sulfide(HS) and weakly by nitrate (NO(3)). Esterase activity weakly reduced by cyanamide. N- hydroxyurea interfers with zinc binding and inhibit activity. Belongs to the alpha-carbonic anhydrase family.
