Abstract:of Yoda1, a small molecule Piezo1 activator, and identify stretch-induced conformational rearrangements of the blades. Yoda1 binding uncouples two adjacent Piezo repeats, facilitating stretch-induced blade motions, and alters long-range residue-residue contacts between pore and blades, as evidenced by Yoda1-induced channel activation of a mechanically-insensitive mutant. In addition, cation-selective fenestrations allow potassium, not chloride, ions to enter a pore vestibule. Our work reveals the structural ba… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
