Name Sarcoplasmic/endoplasmic reticulum calcium ATPase 2
Description Not Available
Synonyms
  1. Calcium pump 2
  2. Calcium-transporting ATPase sarcoplasmic reticulum type, slow twitch skeletal muscle isoform
  3. Endoplasmic reticulum class 1/2 Ca(2+) ATPase
  4. SERCA2
  5. SR Ca(2+)-ATPase 2
Gene Name ATP2A2
Protein Type Enzyme
Biological Properties
General Function Involved in ATP binding
Specific Function This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Isoform 2 is involved in the regulation of the contraction/relaxation cycle.
