^{Ca2+ ATPase}

^{Ca2+ ATPase is a protein which enables active transport of Ca2+ across the membrane of cells. This active transport allows the cells to maintain a low concentration of Ca2+ ions in the cytostol which is important for proper inter-cellular signalling.}

^{Hydrolysis of ATP is the powerhouse for this process, as it allows the binding of Ca2+ ions with a ratio of one ATP hydrolysed for each Ca2+ ion bound.}

^{Here you can see Ca2+ATPase in a cellular membrane.}
