Sarcoplasmic/Endoplasmic Reticulum Calcium ATPase 2

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (1042 aa, ~115 kDa) is encoded by the human ATP2A2 gene. This protein plays a role in both heart contraction and ATP hydrolysis.

**Synonyms:** - ATP2A2 - Calcium Pump 2 - Calcium-Transporting ATPase Sarcoplasmic Reticulum Type, Slow Twitch Skeletal Muscle Isoform - Cardiac Ca2+ ATPase - EC 3.6.3.8, Formerly - EC 7.2.2.10 - Endoplasmic Reticulum Class 1/2 Ca(2+) ATPase - SERCA2 - SR Ca(2+)-ATPase 2
