Ryanodine receptors (RyRs) are calcium release channels expressed in the sarco-endoplasmic reticula of many cell types including cardiac and skeletal muscle cells. In recent years, Ca2+ leak through RyRs has been implicated as a major contributor for development of diseases including heart failure, muscle myopathies, Alzheimer’s disease and diabetes, making it an important therapeutic target. Recent mammalian RyR1 cryo-EM structures of multiple functional states have clarified long-standing questions including the architecture of the transmembrane pore and cytoplasmic domains, location and architecture of the channel gate, ligand binding sites and the gating mechanism. As we advance toward complete models of RyRs this new information enables determination of domain-domain interfaces and the location and structural effects of disease-causing RyR mutations.
