Study determined the three-dimensional structure of rabbit RyR2 in complex with the regulatory protein FKBP12.6 (show FKBP1B Antibodies) in the closed state at 11.8 A resolution using cryo-electron microscopy and built an atomic model of RyR2.
Two regions of the ryanodine receptor (show RYR3 Antibodies) calcium channel are involved in Ca(2 (show CA2 Antibodies)+)-dependent inactivation
[REVIEW] The efficacy of divalent calcium ion (Ca2 (show CA2 Antibodies)+) release in the myocardium depends on the amount of Ca2 (show CA2 Antibodies)+ loaded into the Ca2 (show CA2 Antibodies)+ store and the way in which this Ca2 (show CA2 Antibodies)* load influences the activity of the ryanodine receptor (show RYR3 Antibodies) Ca2+ release channel (RyR2).
There were substantial transmural gradients in Cav1.2 (show CACNA1C Antibodies), KChIP2 (show KCNIP2 Antibodies), ERG (show KCNH2 Antibodies), KvLQT1 (show KCNQ1 Antibodies), Kir2.1 (show KCNJ2 Antibodies), NCX1 (show SLC8A1 Antibodies), SERCA2a (show ATP2A2 Antibodies) and RyR2 at the mRNA and, in some cases, protein level-in every case the mRNA or protein was more abundant in the epicardium than the endocardium.
phosphorylation and K201 acted similarly to change the conformation of RyR1/2 and regulate FKBP12/12.6 binding.
Five of the 19 patients (26.3%) had either a pathogenic variant or a likely pathogenic variant in MYBPC3 (show MYBPC3 Antibodies) (n=1), MYH7 (show MYH7 Antibodies) (n=1), RYR2 (n=2), or TNNT2 (show TNNT2 Antibodies) (n=1). All five variants were missense variants that have been reported previously in patients with channelopathies or cardiomyopathies
RYR2 variants show possible pathogenic Fibrosis of the Cardiac Conduction system.
The most common form of CPVT is due to autosomal dominant variants in the cardiac ryanodine receptor gene (RYR2).
Common variants rs790899 and rs1891246 of RYR2 were significantly associated with HG and weight loss.
The left atrium / right atrium expression ratio was significantly increased in Atrial fibrillation for ryanodine receptor 2 - gene related to calcium uptake and release, and located on the sarcoplasmic reticulum membrane.
a direct interaction exists between RyR2 and CSQ2, is reported.
In a national cohort of RyR2 mutation-positive CPVT patients, SCD (show SCD Antibodies), ASCD and syncope were presenting events in the majority of probands and also occurred in 36% of relatives identified through family screening.
We identified a variant in the RYR2 gene (NM_001035) which involved a change of a glycine to an arginine in position155 of the gene product (c.463G > A, p.Gly155Arg, p.G155R). This RYR2 gene mutation is a novel rare genetic variant as it was not present in any of the international databases consulted.
Data suggest that post-translational modifications (phosphorylation, oxidation, and nitrosylation) of RyR2 (ryanodine receptor 2) occur downstream of production of amyloid beta-peptides through ADRB2 (beta2-adrenergic receptor (show ADRB2 Antibodies)) Ca2 (show CA2 Antibodies)+ signaling cascade that activates PKA (protein kinase A).
The unique properties of the CaM-F142L mutation may provide novel clues on how to suppress excessive RyR2 Ca(2 (show CA2 Antibodies)+) release by manipulating the CaM-RyR2 interaction.
Genetically altered mice with congenitally leaky RyR2 exhibited premature and severe defects in synaptic plasticity, behavior and cognitive function.
A 3-fold increase in the junctophilin-2 (show JPH2 Antibodies) to RyR2 ratio is compatible with direct inhibition of RyR2 opening by junctophilin-2 (show JPH2 Antibodies) to intrinsically stabilize the Ca2 (show CA2 Antibodies)+ signaling properties of the junction and thus the contractile function of the cell.
the coexistence of leaky RYR2 mutations with other genes that enhance epilepsy or cardiac arrhythmia establish RYR2 as a strong additional genetic candidate for sudden death risk.
the RyR2 G357S mutation increases the store overload induced Ca2 (show CA2 Antibodies)+ release (SOICR) activity by reducing the thresholds for SOICR activation and termination and increasing the fractional Ca2 (show CA2 Antibodies)+ release.
Arrhythmic effects of Epac (show RAPGEF3 Antibodies)-mediated ryanodine receptor (show RYR3 Antibodies) activation in Langendorff-perfused murine hearts
K4750Q mutation causes three RyR2 defects: hypersensitization to activation by cytosolic Ca2 (show CA2 Antibodies)+, loss of cytosolic Ca2 (show CA2 Antibodies)+/Mg2 (show MCOLN1 Antibodies)+-mediated inactivation, and hypersensitization to luminal Ca2 (show CA2 Antibodies)+ activation.
InsP3 dependent sarcoplasmic reticulum-Ca2 (show CA2 Antibodies)+ flux constitute the main mechanism of functional crosstalk between InsP3R2 (show ITPR2 Antibodies) and RyR2 resulting in more Ca2 (show CA2 Antibodies)+ sensitized RyRs to trigger subsequent Ca2 (show CA2 Antibodies)+-induced Ca2 (show CA2 Antibodies)+ release activation.
The heart contraction is controlled by the Ca2 (show CA2 Antibodies)+-induced Ca2 (show CA2 Antibodies)+ release between L-type Ca2 (show CA2 Antibodies)+ channels and ryanodine receptors. RyRs became more sensitive to Ca2 (show CA2 Antibodies)+ triggers without FKBP12.6 (show FKBP1B Antibodies), leading to ventricular arrthymias.
Allele-specific silencing of RYR2 prevents life-threatening arrhythmias in genetic carriers.
Redox modification of RyR2 synergistically with CaMKII (show CAMK2G Antibodies) phosphorylation modulates reperfusion arrhythmias.
This gene encodes a ryanodine receptor found in cardiac muscle sarcoplasmic reticulum. The encoded protein is one of the components of a calcium channel, composed of a tetramer of the ryanodine receptor proteins and a tetramer of FK506 binding protein 1B proteins, that supplies calcium to cardiac muscle. Mutations in this gene are associated with stress-induced polymorphic ventricular tachycardia and arrhythmogenic right ventricular dysplasia.
