ATP2B3

A gene on chromosome Xq28 that encodes a magnesium-dependent P-type ion transport ATPase, which forms an aspartyl phosphate intermediate during the reaction cycle. P-type primary ion transport ATPases remove bivalent calcium ions from eukaryotic cells against very large concentration gradients, and play a key role in intracellular calcium homeostasis.
