Invitrogen™ Human RyR3 (aa 1262-1338) Control Fragment Recombinant Protein

RYR3 is a ryanodine receptor, which functions to release calcium from intracellular storage for use in many cellular processes. RYR3 is involved in skeletal muscle contraction by releasing calcium from the sarcoplasmic reticulum followed by depolarization of T-tubules. Two transcript variants encoding different isoforms of RYR3 have been found. RYR3 mediates calcium channel release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm in muscle and plays a role in triggering muscle contraction. Further, RYR3 may also regulate Ca(2+) release by other calcium channels, as well as Ca(2+) release from the endoplasmic reticulum in non-muscle cells. RYR3 also contributes to cellular calcium ion homeostasis. Plays a role in cellular calcium signaling. Diseases associated with RYR3 include Central Core Disease and Arrhythmogenic Right Ventricular Dysplasia 2.
