About This Section Entrez Gene summary for CA2 : CA2 is one of several (at least 7) isozymes of carbonic anhydrase. Carbonic anhydrase catalyzes reversible hydration of carbon dioxide. Defects in this enzyme are associated with osteopetrosis and renal tubular acidosis. (provided by RefSeq, Jul 2008) UniProtKB/Swiss-Prot: CAH2_HUMAN, P00918 Function : Essential for bone resorption and osteoclast differentiation (By similarity). Reversible hydration of carbondioxide. Can hydrate cyanamide to urea. Involved in the regulation of fluid secretion into the anterior chamber of the eye summary
for CA2 : Carbonic anhydrases are zinc-containing enzymes belonging to the lyases family, and are primarilyresponsible for catalyzing the reversible hydration of carbon dioxide to form bicarbonate (HCO3-) andhydrogen (H+) ions. There are several different carbonic anhydrase isoforms; these can be broadly groupedinto cytosolic (CA I, CA II, CA III, CA VII, CA XIII), mitochondrial (CA VA, CA VB), secreted (CA VI) andmembrane-associated (CA IV, CA IX, CA XII, CA XIV) carbonic anhydrases. The functions of the remainingcarbonic anhydrases are yet to be elucidated. Expression of the membrane-bound carbonic anhydrase, CA IX,has been reported in hypoxic tumors where its activity is linked to promoting survival of tumor cells andaiding cancer progression. This is thought to occur through the carbonic anhyrase-mediated production ofbicarbonate ions, which neutralizes the abnormally acidic pH of the extracellular environment induced duringhypoxia. Furthermore, as CA IX is a hypoxia- and HIF-1-inducible enzyme, its expression can be used as abiomarker for hypoxic tumors. Gene Wiki entry for CA2 (Carbonic anhydrase II)

CA2 for disorders About GeneDecksing OMIM gene information: 611492 OMIM disorders : 259730 UniProtKB/Swiss-Prot: CAH2_HUMAN, P00918
Defects in CA2 are the cause of osteopetrosis autosomal recessive type 3 (OPTB3) [MIM:259730]; also known as osteopetrosis with renal tubular acidosis, carbonic anhydrase II deficiency syndrome, Guibaud-Vainsel syndrome or marble brain disease. Osteopetrosis is a rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. The disorder 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. Autosomal recessive osteopetrosis is usually associated with normal or elevated amount of non-functional osteoclasts. OPTB3 is associated with renal tubular acidosis, cerebral calcification (marble brain disease) and in some cases with mental retardation 20/70 diseases for CA2 (see all 70 ): About MalaCards renal tubular acidosis osteopetrosis, autosomal recessive 3, with renal tubular acidosis osteopetrosis osteopetrosis autosomal recessive 3 hypoxia open-angle glaucoma multifocal fibrosclerosis myxopapillary ependymoma giant cell tumor choroid plexus carcinoma ocular hypotension proliferative vitreoretinopathy primary biliary cirrhosis sjogren's syndrome nephrocalcinosis metabolic disorders gliosis cystic fibrosis portal hypertension glaucoma 4 diseases from the University of Copenhagen DISEASES database for CA2 :Renal tubular acidosis Osteopetrosis Glaucoma Metabolic acidosis 10/56 Novoseek disease relationships for CA2 gene (see all 56 ) About this table
