Regulation of Release of Sequestered Calcium Ion Into Cytosol by Sarcoplasmic Reticulum
Any Process That Modulates the Rate Frequency or Extent of Release of Sequestered Calcium Ion Into Cytosol by the Sarcoplasmic Reticulum the Process in Which the Release of Sequestered Calcium Ion by Sarcoplasmic Reticulum Into Cytosol Occurs Via Calcium Release Channels.
Negative Regulation of Ryanodine Sensitive Calcium Release Channel Activity
Any Process That Decreases the Activity of a Ryanodine Sensitive Calcium Release Channel. the Ryanodine Sensitive Calcium Release Channel Catalyzes the Transmembrane Transfer of a Calcium Ion by a Channel That Opens When a Ryanodine Class Ligand Has Been Bound by the Channel Complex or One of Its Constituent Parts.
A Fine Reticular Network of Membrane Limited Elements That Pervades the Sarcoplasm of a Muscle Cell; Continuous Over Large Portions of the Cell and with the Nuclear Envelope; That Part of the Endoplasmic Reticulum Specialized For Calcium Release Uptake and Storage.
