This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to an endomembrane compartment. ATP + Ca(2+)(in) + H2O = ADP + Ca(2+)(out) + H(+) + phosphate Induced by cadmium. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIA subfamily.
