    Based on the structural similarity to voltage-gated potassium channels, the voltage-sensing domain in the TRP channels is hypothesized to be comprised of positively charged amino acids distributed within the transmembrane segments S1-S4. Our data provide the first functional evidence that, despite the highly conserved nature of S4 and the S4-S5 linker, the mechanisms of temperature and chemical sensitivity in TRPV1 appear to utilize different residues from those in TRPV2 and TRPV3, which indicates that these mechanisms are not fully conserved throughout thermosensitive TRPV channels. This conclusion is further supported by our finding that one specific mode of chemical activation of TRPV1 is separable from other activation mechanisms and depends on one basic residue in the S4/S4-S5 domain
