The ryanodine receptors (RyRs) are found on intracellular Ca2+ storage/release organelles. The family of RyR genes encodes three highly related Ca2+ release channels: RyR1, RyR2 and RyR3, which assemble as large tetrameric structures. These RyR channels are ubiquitously expressed in many types of cells and participate in a variety of important Ca2+ signaling phenomena (neurotransmission, secretion, etc.). In addition to the three mammalian isoforms described below, various nonmammalian isoforms of the ryanodine receptor have been identified [2]. The function of the ryanodine receptor channels may also be influenced by closely associated proteins such as the tacrolimus (FK506)-binding protein, calmodulin [3], triadin, calsequestrin, junctin and sorcin, and by protein kinases and phosphatases.
