MSH: Cation-transporting proteins that utilize the energy of ATP hydrolysis for the transport of CALCIUM. They differ from CALCIUM CHANNELS which allow calcium to pass through a membrane without the use of energy.,CSP: family of ATP-driven, transmembrane molecular pumps which maintain concentration gradients of calcium across a variety of cell membranes, the most notable being sarcoplasmic reticulum term not valid for FY 92.
