Background
ATP2C2, also known as secretory pathway Ca2+/Mn2+-ATPase (SPCA) 2, belongs to the family of P-type cation transport ATPases. This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of the calcium from the cytosol to the Golgi lumen. Defects in the related gene ATP2C1 cause Hailey-Hailey disease, for which ATP2C2 does not compensate, suggesting that ATP2C2 plays other physiological roles. Unlike ATP2C1, ATP2C2 has a much more restricted expression pattern and displays a higher maximal turnover rate for overall Ca2+-ATPase reaction and a lower apparent affinity for cytosolic Ca2+ activation of phosphorylation. Overexpression of ATP2C2 in mammary tumors result a Ca2+ influx via the store-operated Ca2+ channel ORAI1 and independent of the STIM1 and STIM2 sensors.Synonyms: ATP2C2, ATPase 2C2, Calcium-transporting ATPase type 2C member, EC=3.6.3.8, KIAA0703, SPCA2, Secretory pathway Ca(2+)-ATPase 2
