Data for Fig 2 & Fig3a-c

Electrophysiological data used for Fig 2 and Fig 3a-c. The file include data for current amplitudes and normalized responses obtained by repeated heat stimulation (five times) from Xenopus laevis oocytes expressing TRPV1 from extant and ancestral clawed frog species. A basal current amplitude was obtained in a five-second duration just before each heat stimulation. If the maximum current amplitude was smaller than 0.5 μA, the current data obtained from such oocytes was excluded from analysis since we could not precisely judge the responses of TRPV1 to repeated heat stimulation.
