A carbonic anhydrase and transmembrane protein that consists of an N-terminal PROTEOGLYCAN-like domain, a catalytic region, a single-pass transmembrane domain, and a short intracellular tail. It functions as a dimer and is expressed primarily by cells of the GASTROINTESTINAL TRACT; BILE DUCT EPITHELIUM; and GALL BLADDER. It is expressed at high levels in many solid tumors, especially CLEAR CELL RENAL CARCINOMA, in response to CELL HYPOXIA. |
