    FAMILY
  • ryanodine receptor family
  • CATEGORY receptor , transport channel
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • controlling intracellular Ca2+ levels by releasing Ca2+ from the myocardial sarcoplasmic reticulum and required for excitation-contraction coupling in cardiac muscle
  • playing a determinant role in the treshold for store-overloaded-induced calcium release and consequently for the sarcoplasmic calcium content
  • with SERCA2A (ATP2A2 variant A) is involved in vasoconstriction in pulmonary arterial smooth muscle (Clark 2010)
  • RTN1 and RYR2 might act as functional partners in the regulation of cytosolic Ca(2+) dynamics the in neurons
