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 WebData indicate that phospholamban (PLB) is not involved in heat generation and that sarcolipin (SLN) alone is responsible for muscle thermogenesis. PLN is a critical target for CaMKII effects on FFR, while CaMKII effects on frequency-dependent acceleration of relaxation partially require PLN-alternative targets.

WebApr 13, 2024 · IntroductionObscurin (720–870 kDa) is a giant cytoskeletal and signaling protein that possesses both structural and regulatory functions in striated muscles. Immunoglobulin domains 58/59 (Ig58/59) of obscurin bind to a diverse set of proteins that are essential for the proper structure and function of the heart, including giant titin, novex … 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 ]. biweekly interest calculator

WebPhospholamban (PLN) plays a key role in calcium handling in heart muscle cells and as such impacts on proper contraction and relaxation of the heart. Carriers of the PLN p.Arg14del pathogenic variant have a high risk of developing dilated cardiomyopathy (DCM) and/or arrhythmogenic cardiomyopathy (ACM) that may develop into heart failure. WebData suggest phospholamban (PLN) gene is a rare cause of cardiomyopathy in African patients. Phospholamban and sarcolipin are membrane proteins that differentially … WebPhospholamban (PLN) is a 52 amino acid integral membrane protein of the sarcoplasmic reticulum (SR) that exists in both monomeric and pentameric forms. In its unphosphorylated state, PLN inhibits the SR Ca (2+) ATPase (SERCA). This inhibition is relieved when PLN is phosphorylated as a result of β-adrenergic stimulation of the heart. date in dd-mmm-yyyy format
