Reversible hydration of carbon dioxide. Participates in pH regulation. May be involved in the control of cell proliferation and transformation. Appears to be a novel specific biomarker for a cervical neoplasia. Forms oligomers linked by disulfide bonds. By hypoxia. Expressed primarily in carcinoma cells lines. Expression is restricted to very few normal tissues and the most abundant expression is found in the epithelial cells of gastric mucosa. Inhibited by coumarins, saccharin, sulfonamide derivatives such as acetazolamide (AZA) and Foscarnet (phosphonoformate trisodium salt). Belongs to the alpha-carbonic anhydrase family.
