Phospholamban, also known as PLN or PLB, is a micropeptide protein that in humans is encoded by the PLN gene. Phospholamban is a 52-amino acid integral membrane protein that regulates the calcium (Ca ) pump in cardiac muscle cells. See more This protein is found as a pentamer and is a major substrate for the cAMP-dependent protein kinase (PKA) in cardiac muscle. In the unphosphorylated state, phospholamban is an inhibitor of cardiac muscle … See more Gene knockout of phospholamban results in animals with hyperdynamic hearts, with little apparent negative consequence. Mutations in this gene are a cause of inherited human See more • PDBe-KB provides an overview of all the structure information available in the PDB for Human Cardiac phospholamban See more Phospholamban was discovered by Arnold Martin Katz and coworkers in 1974.
