The regulation of calcium levels across the membrane of the sarcoplasmic reticulum involves the interplay of many membrane proteins. Phospholamban is a 52 residue integral membrane protein that is involved in reversibly inhibiting the Ca(2+) pump and regulating the flow of Ca ions across the sarcoplasmic reticulum membrane during muscle contraction and relaxation [1]. Phospholamban is thought to form a pentamer in the membrane [1].	Domain
