Carbonic Anhydrase IX (CAIX) is an enzyme that plays a crucial role in regulating pH within cells and tissues. It is a member of the carbonic anhydrase family, which catalyzes the reversible hydration of carbon dioxide. CAIX is overexpressed in many types of cancer cells, particularly in hypoxic conditions where oxygen levels are low. This overexpression is often associated with a poor prognosis, making CAIX a potential target for cancer therapy.
