General annotation (Comments)

Function

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to an endomembrane compartment.

Catalytic activity

ATP + H2O + Ca2+(Cis) = ADP + phosphate + Ca2+(Trans).

Subcellular location

Membrane; Multi-pass membrane protein.

Sequence similarities

Belongs to the cation transport ATPase (P-type) family. Type IIA subfamily.
