Oligomeric Interactions between Phospholamban Molecules Regulate Ca-ATPase Activity in Functionally Reconstituted Membranes

Phospholamban (PLB) is a major target of the β-adrenergic cascade in the heart, and functions as an endogenous inhibitor of Ca-ATPase transport activity. To identify whether oligomeric interactions between PLB molecules are involved in regulating Ca-ATPase transport activity, we have investigated fu...
