The calcium ATPase is a protein composed of 1001 aminoacids.

The protein is very rich in <scene name='60/604489/Alpha_regions/1'>alpha helices regions</scene>. It contains <scene name='60/604489/~~Transmembrane_domain~~/1'>10 transmembrane alpha helices</scene>, and three of them line a channel that spans the lipid bilayer and that allows calcium to pass through membranes. It also contains too cytoplasmic loops between the thransmembrane helices. When the protein isn’t phosphorylated, two of the transmembrane helices are disrupted and form a cavity that can bind two molecules of calcium.
