TRPM2 | Transient Receptor Potential Cation Channel Subfamily M Member 2

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

Topology:
Most TRP channels are composed of 6 transmembrane domains (helices) with intracellular N- and C-termini, non-selectively permeable to various cations
