  • FunctionCalcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering cardiac muscle contraction. Aberrant channel activation can lead to cardiac arrhythmia. In cardiac myocytes, calcium release is triggered by increased Ca(2+) levels due to activation of the L-type calcium channel CACNA1C. The calcium channel activity is modulated by formation of heterotetramers with RYR3. Required for cellular calcium ion homeostasis. Required for embryonic heart development.
  • Tissue specificityDetected in heart muscle (at protein level). Heart muscle, brain (cerebellum and hippocampus) and placenta.
  • Involvement in diseaseFamilial arrhythmogenic right ventricular dysplasia 2
    Ventricular tachycardia, catecholaminergic polymorphic 1, with or without atrial dysfunction and/or dilated cardiomyopathy
  • Sequence similaritiesBelongs to the ryanodine receptor (TC 1.A.3.1) family. RYR2 subfamily.
    Contains 3 B30.2/SPRY domains.
    Contains 5 MIR domains.
  • Developmental stageExpressed in myometrium during pregnancy.
  • DomainThe calcium release channel activity resides in the C-terminal region while the remaining part of the protein resides in the cytoplasm.
  • Post-translational
    Channel activity is modulated by phosphorylation. Phosphorylation at Ser-2808 and Ser-2814 increases the open probability of the calcium channel. Phosphorylation is increased in failing heart, leading to calcium leaks and increased cytoplasmic Ca(2+) levels.
    Phosphorylation at Ser-2031 by PKA enhances the response to lumenal calcium.
  • Cellular localizationSarcoplasmic reticulum membrane. Membrane. The number of predicted transmembrane domains varies between orthologs, but both N-terminus and C-terminus seem to be cytoplasmic.

Thank you for your reply.

We have a number of phospho specific antibodies in our catalog, but ab59225 is the only phospho specific antibody we have to Ryanodine Receptors.

In order to determine specifically which residue...
