RNA expression pattern

Sarcoplasmic/endoplasmic reticulum calcium ATPase 1 is an enzyme that in humans is encoded by the ATP2A1 gene.[1]

This gene encodes one of the SERCA Ca2+-ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells. This enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen, and is involved in muscular excitation and contraction. Mutations in this gene cause some autosomal recessive forms of Brody disease, characterized by increasing impairment of muscular relaxation during exercise. Alternative splicing results in two transcript variants encoding different isoforms.[1]

Interactions

ATP2A1 has been shown to interact with PLN[2][3][4] and SLN.[2][5]
