Mechanical stimulation of Piezo channels gives rise to a mechanically-activated (MA) present, which speedily decays because of rapidly inactivation (Lewis et al., 2017; Gottlieb et al., 2012). Disease-linkedZheng et al. eLife 2019;8:e44003. DOI: https://doi.org/10.7554/eLife.1 ofResearch articleStructural Biology and Molecular Biophysicsmutations in Piezo1 and Piezo2 particularly influence this inactivation approach, suggesting that the typical timing of MA present decay is significant for animal physiology (Wu et al., 2017a). Moreover, a prolongation of Piezo2 inactivation in somatosensory neurons of tactile-specialist birds suggests that inactivation is involved in the modulation of complicated behaviors (Schneider et al., 2017; Anderson et al., 2017; Schneider et al., 2014). Inactivation is significantly affected by the known modulators of Piezo1: Yoda1 and Jedi1/2 (Lacroix et al., 2018; Wang et al., 2018; Evans et al., 2018; Syeda et al., 2015). However, regardless of its significance for channel function, physiology and pathophysiology, the mechanism of Piezo inactivation remains unknown. Functional Piezo channels are homo-trimers that adopt a exceptional propeller-like architecture comprising a central C-terminal ion-conducting pore and three peripheral N-terminal blades (Figure 1A) (Guo and MacKinnon, 2017; Saotome et al., 2018; Zhao et al., 2018). Each blade is composed of 36 transmembrane (TM) segments and is thought to contribute to sensing tension within the membrane (Guo and MacKinnon, 2017; Haselwandter and MacKinnon, 2018). The pore region, which contains an outer pore helix (OH), an inner pore helix (IH), an additional.
