Plasma membrane Ca ATPase (PMCA) is a transport protein in the plasma membrane of cells that serves to remove calcium (Ca ) from the cell. It is vital for regulating the amount of Ca within cells. In fact, the PMCA is involved in removing Ca from all eukaryotic cells. There is a very large transmembrane … See more Ca ATPase is a form of P-ATPase that transfers calcium after a muscle has contracted. The two kinds of calcium ATPase are: • Plasma membrane Ca ATPase (PMCA) • Sarcoplasmic reticulum See more In myocytes (muscle cells) Ca is normally sequestered (isolated) in a specialized form of endoplasmic reticulum (ER) called sarcoplasmic reticulum (SR).
