Conformational changes in heat- and proton-sensing ion channel in centipedes

Structural analyses, patch-clamp recordings and molecular dynamic simulations of the heat and proton sensor BRTNaC1 channel in centipedes reveal a ‘twist the wrist’ mechanism induced by proton activation. Heat induces broad conformational changes in BRTNaC1, including rotation and shift in the transmembrane helices to open this channel.

期刊介绍： Nature Structural & Molecular Biology is a comprehensive platform that combines structural and molecular research. Our journal focuses on exploring the functional and mechanistic aspects of biological processes, emphasizing how molecular components collaborate to achieve a particular function. While structural data can shed light on these insights, our publication does not require them as a prerequisite.
