CC -!- FUNCTION: Key regulator of striated muscle performance by acting as the
CC major Ca(2+) ATPase responsible for the reuptake of cytosolic Ca(2+)
CC into the sarcoplasmic reticulum. Catalyzes the hydrolysis of ATP
CC coupled with the translocation of calcium from the cytosol to the
CC sarcoplasmic reticulum lumen. Contributes to calcium sequestration
CC involved in muscular excitation/contraction.
CC {ECO:0000250|UniProtKB:Q8R429}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + Ca(2+)(in) + H2O = ADP + Ca(2+)(out) + H(+) + phosphate;
CC Xref=Rhea:RHEA:18105, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC ChEBI:CHEBI:456216; EC=7.2.2.10;
CC Evidence={ECO:0000250|UniProtKB:P04191};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:18106;
CC Evidence={ECO:0000250|UniProtKB:P04191};
CC -!- ACTIVITY REGULATION: Inhibited by sarcolipin (SLN), phospholamban (PLN)
CC and myoregulin (MRLN) (By similarity). Enhanced by DWORF; DWORF
CC increases activity by displacing sarcolipin (SLN), phospholamban (PLN)
CC and myoregulin (MRLN) (By similarity). {ECO:0000250|UniProtKB:P04191,
CC ECO:0000250|UniProtKB:Q8R429}.
CC -!- SUBUNIT: Interacts with sarcolipin (SLN) (By similarity). Interacts
CC with phospholamban (PLN) (By similarity). Interacts with myoregulin
CC (MRLN). Interacts with DWORF (By similarity). Interacts VMP1 (By
CC similarity). {ECO:0000250|UniProtKB:O14983,
CC ECO:0000250|UniProtKB:Q8R429}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P04191}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P04191}. Sarcoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P04191}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P04191}.
CC -!- DOMAIN: Ca(2+) and ATP binding cause major rearrangements of the
CC cytoplasmic and transmembrane domains. According to the E1-E2 model,
CC Ca(2+) binding to the cytosolic domain of the pump in the high-affinity
CC E1 conformation is followed by the ATP-dependent phosphorylation of the
CC active site Asp, giving rise to E1P. A conformational change of the
CC phosphoenzyme gives rise to the low-affinity E2P state that exposes the
CC Ca(2+) ions to the lumenal side and promotes Ca(2+) release.
CC Dephosphorylation of the active site Asp mediates the subsequent return
CC to the E1 conformation. {ECO:0000250|UniProtKB:P04191}.
CC -!- DOMAIN: PLN and SLN both have a single transmembrane helix; both occupy
CC a similar binding site on ATP2A1 that is situated between the ATP2A1
CC transmembrane helices. {ECO:0000250|UniProtKB:P04191}.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IIA subfamily. {ECO:0000305}.
