SERCA (Sarcoplasmic Reticulum Calcium ATPase)

SERCA, or Sarcoplasmic Reticulum Calcium ATPase, is a specialized protein located in the muscle cell's internal structure called the sarcoplasmic reticulum. Its main role is to pump calcium ions from the cytoplasm back into the sarcoplasmic reticulum after muscle contraction. Using energy from ATP, SERCA helps muscles relax by removing calcium from the cell’s interior, ensuring proper muscle function. This process is essential for controlling muscle contractions and maintaining overall muscle health, allowing muscles to contract and relax efficiently during movement.
