Human Ryanodine Receptor 3, RYR3 ELI

Calcium Channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm in muscle and thereby plays a role in triggering muscle contraction.

May regulate Ca(2+) release by other calcium Channels.

Calcium Channel that mediates Ca(2+)-induced Ca(2+) release from the endoplasmic reticulum in non-muscle cells.

Contributes to cellular calcium ion homeostasis (By similarity).

Plays a role in cellular calcium signaling.
