WebPhospholamban is a 52- amino acid integral membrane protein that regulates the calcium (Ca 2+) pump in cardiac muscle cells. [4] Function [ edit] This protein is found as a pentamer and is a major substrate for the cAMP-dependent protein kinase ( PKA) in cardiac muscle. WebAbstract Phospholamban is a 52-amino-acid protein that assembles into a pentamer in sarcoplasmic reticulum membranes. The protein has a role in the regulation of the resident calcium ATPase through an inhibitory association that can be reversed by phosphorylation.
