• TRPV3

    Recordings from a HEK cell expressing TRPV3 were made with the Patchliner showing activation by heat.

TRPV3 | Transient Receptor Potential Cation Channel Subfamily V Member 3

Family:
Transient  receptor potential channels

Subgroups:
TRPC (TRPC1–TRPC7), TRPV (TRPV1-TRPV6), TRPA1, TRPM (TRPM1–TRPM8), TRPP (TRPP1–TRPP3, PKD1, PKDREJ, PKDL1–PKDL3), TRPML (TRPML1–TRPML3), TRPN

Data and Applications

TRPV3 - Temperature Activation

icon pl   Patchliner data and applications:TRPV3 Patchliner
Cells were kindly supplied by Millipore.

Recordings from a HEK cell expressing TRPV3 were made with the Patchliner showing activation by heat. External solution was heated inside the Patchliner pipette to the temperature shown and applied to the cells. TRPV3 was activated at temperatures ≥ 38°C.
