However, if calcium within the SR rises too high, more calcium binds to the calsequestrin and therefore it binds to the junctin-triadin-RyR complex less tightly.

    Recently, the basis for the critical role of the SR in calcium signaling has started to emerge. In: Berne RM, ed. The main role of these proteins is to anchor calsequestrin see above to the ryanodine receptor.

    J Cell Biol. Feb;(4) The Ca2+-release channel/ryanodine receptor is localized in junctional and corbular sarcoplasmic reticulum in cardiac. The receptor is confined to the sarcoplasmic reticulum (SR) where it is localized to interior and peripheral junctional SR and the corbular SR, but it is absent from.
