Disease

[CAH2_HUMAN] 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.^[1] ^[2] ^[3] ^[4] ^[5]

Function

[CAH2_HUMAN] 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.^[6] ^[7]

Publication Abstract from PubMed

Inhibition of human carbonic anhydrase IX (hCA IX) has shown to be therapeutically advantageous for treating many types of highly aggressive cancers. However, designing selective inhibitors for hCA IX has been difficult due to its high structural homology and sequence similarity with off-target hCAs. Recently the use of glucosyl sulfamate inhibitors has shown promise as selective inhibitors for hCA IX. In this study we present five X-ray crystal structures, determined to a resolution of 1.7 A or better, of both hCA II (a ubiquitous CA) and an engineered hCA IX-mimic in complex with selected glucosyl sulfamates and structurally rationalize mechanisms for hCA IX selectivity. Results from this study have allowed us, for the first time, to empirically "map" key interactions of the hCA IX active site in order to establish parameters needed to design novel hCA IX selective inhibitors.
