RyR domain disruption hypersensitizes Ca2+ release in vitro; leaves open whether this mechanism drives clinical arrhythmias or offers targets.
Contact between the N-terminal and central domains of the ryanodine receptor likely closes the Ca2+ channel, while disruption of this contact by peptides or mutations causes hyperactivation and hypersensitization.
Yamamoto et al. (2000) studied this question.
