The human carbonic anhydrase IV (CA4) gene, located on chromosome 17q22, was the first identified membrane-bound isozyme in the 16-member carbonic anhydrase (CA) gene family and contains 1,170 base pairs. The CA4 enzyme is involved in the formation of gastric acid and participates in acid-base homeostasis. CA4 is expressed in normal human stomach tissues. CA4 may serve an important role in gastric cancer (GC) tumorigenesis by inhibiting cellular proliferation via regulating the expression of cell cycle‑associated proteins. CA4 may serve as a diagnostic biomarker and a potential therapeutic target in GC[1].
