Function
This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Transports calcium ions from the cytosol into the sarcoplasmic/endoplasmic reticulum lumen (PubMed:27923914). Contributes to calcium sequestration involved in muscular excitation/contraction
