General annotation (Comments)

Function

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Contributes to calcium sequestration involved in muscular excitation/contraction By similarity.

Catalytic activity

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

Enzyme regulation

Reversibly inhibited by phospholamban (PLN) at low calcium concentrations. Dephosphorylated PLN decreases the apparent affinity of the ATPase for calcium. This inhibition is regulated by the phosphorylation of PLN By similarity.

Subunit structure

Associated with sarcolipin (SLN) and phospholamban (PLN) By similarity.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein. Sarcoplasmic reticulum membrane; Multi-pass membrane protein By similarity.

Sequence similarities

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