WebWe used 9-fluorenylmethyl-oxycarbonyl (Fmoc) solid-phase peptide synthesis to prepare full-length phospholamban (PLB 1-52) and its cytoplasmic (PLB 1-25 K: phospholamban residues 1-25 plus a C-terminal lysine), ... We compared the function (inhibition of the Ca-ATPase in reconstituted membranes) and structure (via CD) of the PLB1-25 amphiphile ... 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 sarcoplasmic reticulum Ca -ATPase (SERCA2) which transports calcium from cytosol into … See more 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 … See more Gene knockout of phospholamban results in animals with hyperdynamic hearts, with little apparent negative consequence. Mutations in this … 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.

WebOct 7, 2013 · Phosphorylation of phospholamban shifts the equilibria, enhancing SERCA function. This mechanism explains why tuning phospholamban’s structural dynamics can modulate SERCA function and may aid in designing innovative therapeutic approaches to heart failure. Abstract WebSep 25, 2024 · The function of phospholamban during catecholamine stimulation of the heart suggests a role for this protein as an internal “brake mechanism,” which allows for … WebApr 29, 2003 · In cardiac cells, phospholamban is a potent inhibitor of sarcoplasmic reticulum calcium (Ca 2+) transport. Overexpression of mutant forms of phospholamban may result in beneficial or detrimental effects on intracellular Ca 2+ handling and cardiac systolic and diastolic function. images of jeff cook alabama
