Carbonic Anhydrase (CA IX) is part of a family of zinc containing metalloproteins that catalyze the reversible hydration of CO2.1  Among these, CA IX is anchored to the cell membrane and is expressed in the human gastrointestinal tract, chiefly in the stomach.1 Data suggest consistent immunoreactivity for anti-CA IX in clear cell renal cell carcinoma (RCC) making it a useful marker for this type of tumor.2
