Molecular mechanisms underlying menthol binding and activation of TRPM8 ion channel

Abstract

Menthol in mints elicits a coolness sensation by selective activation of TRPM8 ion channel. Here authors dock menthol to TRPM8 and systematically validate their menthol binding models with thermodynamic mutant cycle analysis in functional tests, and shed light on TRPM8 activation by menthol at the atomic level.
