SERCA (sarcoplasmic/endoplasmic reticulum Ca2+-ATPase or SR Ca2+-ATPase) is a membrane protein that transports calcium from the cytosol into the sarcoplasmic reticulum (SR) of muscle cells. The SR is a structure which stores calcium in muscle cells, similar to the smooth endoplasmic reticulum of other cells. SERCA is a calcium ATPase-type P-ATPase. It uses energy from ATP to actively transport calcium ions across the SR membrane.

SERCA (sarcoplasmic/endoplasmic reticulum Ca2+-ATPase or SR Ca2+-ATPase) is a membrane protein that transports calcium from the cytosol into the sarcoplasmic reticulum (SR) of muscle cells. The SR is a structure which stores calcium in muscle cells, similar to the smooth endoplasmic reticulum of other cells. SERCA is a calcium ATPase-type P-ATPase. It uses energy from ATP to actively transport calcium ions across the SR membrane.
==Function== SERCA is a P-type ATPase. It resides in the sarcoplasmic reticulum (SR) within myocytes. It is a Ca2+ ATPase that transfers Ca2+ from the cytosol of the cell to the lumen of the SR. This uses energy from ATP hydrolysis during muscle relaxation.
