SERCA2 (human)

SERCA2 an intracellular pump located in the sarcoplasmic or endoplasmic reticula of muscle cells. Possesses a Ca(2+)-ATPase activity. Catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen, and is involved in regulation of the contraction/relaxation cycle. Reversibly inhibited by phospholamban (PLN) at low calcium concentrations. Dephosphorylated PLN decreases the apparent affinity of the ATPase for calcium. This inhibition is regulated by the phosphorylation of PLN. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
