CA XII (N273) polyclonal antibody

Carbonic anhydrases (CA) are a family of ancient zinc metalloenzymes found in almost all living organisms. All CA can be divided into 3 distinct classes (α, β, and γ) that evolved independently and have no significant homology in sequence and overall folding. All functional CA catalyze the reversible hydration of CO2 into HCO3- and H+ and contain a zinc atom in the active sites essential for catalysis. There are many isoforms of CA in mammals and they all belong to the α class. CA12, a member of the α class, is a plasma membrane protein with the catalytic domain in the extracellular space. CA12 is widely expressed in many tissues and is found at high levels in renal cell cancers. Its expression is induced by hypoxia in solid tumors and is considered to be a tumor marker. Genetic mutations in CA12 are associated with hyperchlorhidrosis.
