background:
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.
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.
Subunit:
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.
Tissue Specificity:
Skeletal muscle, fast twitch muscle (type II) fibers.
DISEASE:
Defects in ATP2A1 are the cause of Brody myopathy (BRM) [MIM:601003]. An autosomal recessive myopathy characterized by increasing impairment of relaxation of fast twist skeletal muscle during exercise.
Similarity:
Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIA subfamily.
