Phosphorylation-Dependent Regulation of Ryanodine Receptors
Ryanodine receptors (RyRs), intracellular calcium release channels required for cardiac and skeletal muscle contraction, are macromolecular complexes that include kinases and phosphatases. Phosphorylation/dephosphorylation plays a key role in regulating the function of many ion channels, including RyRs. However, the mechanism by which kinases and phosphatases are targeted to ion channels is not...

متن کاملRyanodine Receptors: Structure
Ryanodine receptors (RyRs) are huge ion channels that are responsible for the release of Ca2 from the sarco/endoplasmic reticulum. RyRs form homotetramers with a mushroom-like shape, consisting of a large cytoplasmic head and transmembrane stalk. Ca2 is a major physiological ligand that triggers opening of RyRs, but a plethora of modulatory proteins and small molecules in the cytoplasm and sarc...
متن کاملRegulation of mammalian ryanodine receptors.
Ryanodine receptors (RyRs) are large, high conductance Ca2+ channels that control the level of intracellular Ca2+ by releasing Ca2+ from an intracellular compartment, the sarco/endoplasmic reticulum. Mammalian tissues express 3 closely related ryanodine receptors (RyRs) known as skeletal muscle (RyR1), cardiac muscle (RyR2) and brain (RyR3). The RyRs are isolated as 30S protein complexes compri...
متن کاملWhat are the consequences of phosphorylation and hyperphosphorylation of ryanodine receptors in normal and failing heart?
Marks and colleagues published some influential results in 2000, suggesting that protein kinase A phosphorylation regulates ryanodine receptor (RyR2) open probability (PoRyR). The authors attributed this to the dissociation of the RyR-associated regulatory protein FKBP12.6.1 They went on to propose that, in failing hearts, RyR2 is hyperphosphorylated, which leads to defective channel function b...
