Inhibition of TRPM8 by reduction of PI(4,5)P2 in intact cells, right panels in A,B and C show cartoon of the method used. A. Whole cell patch clamp measurement from (Daniels et al., 2009) showing inhibition of menthol induced RPM8 currents by the pharmacological PLC activator m-3M3FBS. B. Inhibition of TRPM8 activity by the rapamycin inducible 5-phosphatase from (Varnai et al., 2006). C. Inhibition of TRPM8 activity by depolarization-induced depletion of PI(4,5)P2 in ciVSP expressing cells from (Yudin et al., 2011). Left panel shows a measurement with the active ciVSP, middle panel with an inactive mutant.
