The protein encoded by this gene is one of several isozymes of carbonic anhydrase, which catalyzes reversible hydration of carbon dioxide. Defects in this enzyme are associated with osteopetrosis and renal tubular acidosis. Two transcript variants encoding different isoforms have been found for this gene.

GeneCards Summary for CA2 Gene

CA2 (Carbonic Anhydrase 2) is a Protein Coding gene. Diseases associated with CA2 include Osteopetrosis, Autosomal Recessive 3 and Renal Tubular Acidosis. Among its related pathways are Proximal tubule bicarbonate reclamation and Salivary secretion. Gene Ontology (GO) annotations related to this gene include carbonate dehydratase activity and arylesterase activity. An important paralog of this gene is CA13.

UniProtKB/Swiss-Prot Summary for CA2 Gene

  • Essential for bone resorption and osteoclast differentiation (By similarity). Reversible hydration of carbon dioxide. Can hydrate cyanamide to urea. Involved in the regulation of fluid secretion into the anterior chamber of the eye. Contributes to intracellular pH regulation in the duodenal upper villous epithelium during proton-coupled peptide absorption. Stimulates the chloride-bicarbonate exchange activity of SLC26A6.

Tocris Summary for CA2 Gene

  • Carbonic anhydrases (EC 4.2.1.1) are zinc-containing enzymes belonging to the lyases family, and are primarily responsible for catalyzing the reversible hydration of carbon dioxide to form bicarbonate (HCO3-) and hydrogen (H+) ions.

  • Osteopetrosis, autosomal recessive 3 (OPTB3) [MIM:259730]: A rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. Osteopetrosis occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. Recessive osteopetrosis commonly manifests in early infancy with macrocephaly, feeding difficulties, evolving blindness and deafness, bone marrow failure, severe anemia, and hepatosplenomegaly. Deafness and blindness are generally thought to represent effects of pressure on nerves. OPTB3 is associated with renal tubular acidosis, cerebral calcification (marble brain disease) and in some cases with mental retardation. {ECO:0000269 PubMed:15300855, ECO:0000269 PubMed:1542674, ECO:0000269 PubMed:1928091, ECO:0000269 PubMed:8834238, ECO:0000269 PubMed:9143915}. Note=The disease is caused by variants affecting the gene represented in this entry.
