LMOD1 (Montrer LMOD1 Kits ELISA), SYNPO2 (Montrer SYNPO2 Kits ELISA), PDLIM7 (Montrer PDLIM7 Kits ELISA), PLN, and SYNM (Montrer SYNM Kits ELISA) down-regulation reflect the altered phenotype of smooth muscle cells in vascular disease and could be early sensitive markers of SMC (Montrer DYM Kits ELISA) dedifferentiation.
microRNAs (miRNAs) 1 and 21 bind PLN strongly and relieve PLN inhibition of SERCA (Montrer ATP2A3 Kits ELISA) to a greater extent than a similar length random sequence RNA mixture.
Data suggest phospholamban (PLN) gene is a rare cause of cardiomyopathy in African patients.
Phospholamban and sarcolipin (Montrer SLN Kits ELISA) are membrane proteins that differentially regulate SERCA (Montrer ATP2A3 Kits ELISA) function. (Review)
PLN may be a key molecular player in rigid substrate-induced cellular hypertrophy in eosinophilic esophagitis.
These data suggest that PLN is, at least partially, oligo-ubiquitinated at Lys (Montrer LYZ Kits ELISA)(3) and degraded through Ser (Montrer SIGLEC1 Kits ELISA)(16)-phosphorylation-mediated poly-ubiquitination during heart failure.
hereditary mutants of phospholamban are associated with heart failure [review]
PLN pentamers reduce phosphorylation of monomers at baseline and delay monomer phosphorylation upon PKA stimulation leading to increased interaction of PLN monomers with SERCA2a (Montrer ATP2A2 Kits ELISA).
Phospholamban R14del mutation carriers are at high risk for malignant ventricular arrhythmias and end-stage heart failure, with left ventricular ejection fraction <45% and sustained or nonsustained ventricular tachycardia as independent risk factors.
Although SLN (Montrer SLN Kits ELISA) and PLB binding to SERCA (Montrer ATP2A3 Kits ELISA) have different functional outcomes on the coupling efficiency of SERCA (Montrer ATP2A3 Kits ELISA), both proteins decrease the apparent Ca(2 (Montrer CA2 Kits ELISA)+) affinity of the pump, suggesting that SLN (Montrer SLN Kits ELISA) and PLB inhibit SERCA (Montrer ATP2A3 Kits ELISA) by using a similar mechanism.
Phosphorylation of PLB induces spatial rearrangements between the N- and P-domain elements of proximal Ca-ATPase (Montrer CA-P60A Kits ELISA).
Molecular dynamics simulations of phospholamban in solution and in membrane bilayer show two main features: the presence of two well-defined helical domains at the N- and C-termini, and large-amplitude rigid-body motions of these domains.
The expression of SLN (Montrer SLN Kits ELISA) and PLB mRNA and protein relative to SERCA1 (Montrer ATP2A1 Kits ELISA) or SERCA2 (Montrer ATP2A2 Kits ELISA) was assessed in ventricle, atrium, and skeltal msucle of mouse, rat, rabbit and pig.
A single-dose injection of PLN-targeting locked nucleic acid antisense oligonucleotide improved contractility in pressure overload-induced cardiac dysfunction.
PLN overexpression is associated with severe muscle atrophy and weakness.
the commercially available overexpressing phospholamban mouse phenotypically resembles human Centronuclear myopathy and could be used as a model to test potential mechanisms and therapeutic strategies.
Cardioprotective effects of H2S are mediated through acGMP/PKG (Montrer PRKG1 Kits ELISA)/phospholamban pathway.
combined deletion of Phd2 (Montrer EGLN1 Kits ELISA) and Phd3 (Montrer EGLN3 Kits ELISA) dramatically decreased expression of phospholamban (PLN), resulted in sustained activation of calcium/calmodulin-activated kinase II (CaMKII (Montrer CAMK2G Kits ELISA)), and sensitized mice to chronic beta-adrenergic stress-induced myocardial injury
the N termini of SLN (Montrer SLN Kits ELISA) and PLB influence their respective unique functions
CaMKII (Montrer CAMK2G Kits ELISA)-dependent increase in PLN phosphorylation during reperfusion opposes rather than contributes to ischemia/reperfusion damage.
TNAP (Montrer ALPL Kits ELISA) plays a role in governing the phosphorylation status of phospholamban in the sarcoplasmic reticulum.
Acute expression of R9C mutation of phospholamban in cardiomyocytes was positively inotropic/lusitropic.
Ca(2 (Montrer CA2 Kits ELISA)+) and PLB phosphorylation relieve SERCA (Montrer ATP2A3 Kits ELISA)-PLB inhibition by distinct mechanisms, but both are achieved primarily by structural changes within the SERCA (Montrer ATP2A3 Kits ELISA)-PLB complex, not by dissociation of that complex.
Phosphorylated phospholamban stabilizes a unique conformation of SERCA (Montrer ATP2A3 Kits ELISA) that is characterized by a compact architecture.
Data suggest that phospholamban PLN's conformational equilibrium is central to maintain sarcoplasmic reticulum Ca(2+)-ATPase (Montrer CA-P60A Kits ELISA) SERCA's apparent Ca(2 (Montrer CA2 Kits ELISA)+) affinity within a physiological window.
demonstrate that the role of Arg(9) in phospholamban function is multifaceted: it is important for inhibition of SERCA (Montrer ATP2A3 Kits ELISA), it increases the efficiency of phosphorylation, and it is critical for protein kinase A recognition
The interaction energies between the N-terminal helix of phospholamban and different POPC lipid/cholesterol bilayers quantitatively confirm its stronger interaction with a higher cholesterol-containing membrane.
The lipid bilayer composition influences the regulation of SERCA (Montrer ATP2A3 Kits ELISA) by PLN.
Phospholamban overexpression in rabbit ventricular myocytes does not alter sarcoplasmic reticulum Ca transport.
The protein encoded by this gene is found as a pentamer and is a major substrate for the cAMP-dependent protein kinase in cardiac muscle. The encoded protein is an inhibitor of cardiac muscle sarcoplasmic reticulum Ca(2+)-ATPase in the unphosphorylated state, but inhibition is relieved upon phosphorylation of the protein. The subsequent activation of the Ca(2+) pump leads to enhanced muscle relaxation rates, thereby contributing to the inotropic response elicited in heart by beta-agonists. The encoded protein is a key regulator of cardiac diastolic function. Mutations in this gene are a cause of inherited human dilated cardiomyopathy with refractory congestive heart failure.
