Citation | Journal: Structure / Year: 2022Title: A drug and ATP binding site in type 1 ryanodine receptor. Authors: Zephan Melville / Haikel Dridi / Qi Yuan / Steven Reiken / Anetta Wronska / Yang Liu / Oliver B Clarke / Andrew R Marks / ![]() Abstract: The ryanodine receptor (RyR)/calcium release channel on the sarcoplasmic reticulum (SR) is required for excitation-contraction coupling in skeletal and cardiac muscle. Inherited mutations and stress- ...The ryanodine receptor (RyR)/calcium release channel on the sarcoplasmic reticulum (SR) is required for excitation-contraction coupling in skeletal and cardiac muscle. Inherited mutations and stress-induced post-translational modifications result in an SR Ca leak that causes skeletal myopathies, heart failure, and exercise-induced sudden death. A class of therapeutics known as Rycals prevent the RyR-mediated leak, are effective in preventing disease progression and restoring function in animal models, and are in clinical trials for patients with muscle and heart disorders. Using cryogenic-electron microscopy, we present a model of RyR1 with a 2.45-Å resolution before local refinement, revealing a binding site in the RY1&2 domain (3.10 Å local resolution), where the Rycal ARM210 binds cooperatively with ATP and stabilizes the closed state of RyR1. | |||||||||||||||||||||
