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. See more PLN has been shown to interact with SLN and SERCA1. See more WebThe antibody recognises mono and oligomeric phospholamban when phosphorylated on serine-16 by PKA. Binding of the antibody to its target epitope is blocked in the presence of a phosphopeptide containing the PLB Phospho Ser-16 epitope.

WebPhospholamban. PLN is an SR protein that associates with SERCA 51 and inhibits its Ca 2+ transport rate. Phosphorylation of PLN by either protein kinase A at serine 16 or Ca 2+-calmodulin dependent protein kinase at threonine 17 58 causes PLN to disassociate from SERCA and its inhibitory effect is removed. WebPhospholamban (PLN) is a muscle-specific sarcoplasmic reticulum (SR) Ca-ATPase inhibitor, highly expressed in cardiac muscle [38]. It has two adjacent residues, S16 and T17, identified as the phosphorylation sites for protein kinase A and Ca/calmodulin-dependent kinase II, respectively [ 47 ]. smallest base cabinet width
