Catalytic activity:ATP = 3',5'-cyclic AMP + diphosphate.,cofactor:Binds 2 magnesium ions per subunit.,Disease:Genetic variations in ADCY10 are associated with absorptive hypercalciuria type 2 (HCA2) [MIM:143870]. Absorptive hypercalciuria (AH) is a common cause of calcium oxalate nephrolithiasis. Clinically, AH is characterized by intestinal hyperabsorption of calcium in the presence of normal serum calcium and immunoreactive PTH (iPTH). It is often accompanied by low bone mineral density (BMD), particularly of the lumbar spine. About 50% of patients with AH present with a family history of calcium oxalate nephrolithiasis and hypercalciuria.,enzyme regulation:Activated by manganese or magnesium ions. In the presence of magnesium ions, the enzyme is activated by bicarbonate while in the presence of manganese ions, the enzyme is inhibited by bicarbonate. In the absence of magnesium and bicarbonate, the enzyme is weakly activated by calcium.,Function:Soluble adenylyl cyclase that has a critical role in mammalian spermatogenesis. Produces the cAMP which mediates in part the cAMP-responsive nuclear factors indispensable for maturation of sperm in the epididymis. Induces capacitation, the maturational process that sperm undergo prior to fertilization. May be the bicarbonate sensor. Involved in ciliary beat regulation.,PTM:Cleavage may occur to generate the active 48 kDa form.,similarity:Belongs to the adenylyl cyclase class-4/guanylyl cyclase family.,similarity:Contains 2 guanylate cyclase domains.,subcellular location:Distributed to subcellular compartments containing cAMP targets. Found as a plasma membrane-associated protein, protein concentrated in the perinuclear region and protein colocalized with actin or tubulin.,tissue specificity:Weakly expressed in multiple tissues. Expressed in brain, heart, kidney, liver, lung, pancreas, peripheral blood leukocytes, placenta, skeletal muscle, stomach, thymus, airway epithelial cells, duodenum, jejunum and ileum. Very low level of expression in bone.,
