FunctionEssential for bone resorption and osteoclast differentiation (By similarity). Reversible hydration of carbon dioxide. Can hydrates cyanamide to urea. Involved in the regulation of fluid secretion into the anterior chamber of the eye.
Involvement in diseaseDefects 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.
Sequence similaritiesBelongs to the alpha-carbonic anhydrase family.

ab124687, at 1/250 dilution, staining Carbonic anhydrase 2/CA2 in paraffin-embedded Human kidney tissue by Immunohistochemistry.
Lane 1: Wild-type HAP1 cell lysate (40 µg)
Lane 2: Carbonic anhydrase 2/CA2 knockout HAP1 cell lysate (40 µg)
Lane 3: A431 cell lysate (40 µg)
Lane 4: HEK293 cell lysate (40 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab124687 observed at 32 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab124687 was shown to specifically react with Carbonic anhydrase 2/CA2 when Carbonic anhydrase 2/CA2 knockout samples were used. Wild-type and Carbonic anhydrase 2/CA2 knockout samples were subjected to SDS-PAGE. Ab124687 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1:10,000 dilution respectively and incubated overnight at 4C. Blots were developed with IRDye® 800CW Goat anti-Rabbit IgG (H + L) and IRDye® 680 Goat anti-Mouse IgG (H + L) secondary antibodies at 1:10,000 dilution for 1 hour at room temperature before imaging.
