Ryanodine receptor 3 is one of a class of
ryanodine receptor
Ryanodine receptors (RyR for short) form a class of intracellular calcium channels in various forms of excitable animal tissue like muscles and neurons.
There are three major isoforms of the ryanodine receptor, which are found in different tissu ...
