Sarcoplasmic/endoplasmic reticulum calcium ATPase 3 is an enzyme that in humans is encoded by the ATP2A3 gene.This gene encodes one of the SERCA Ca2+-ATPases which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of cells. SERCA3 expression was originally described as non-muscular but was recently observed in cardiomyocyte.
