TRPC5 | Transient Receptor Potential Cation Channel Subfamily C Member 5
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
TRPC5: Background information
TRPC5, aslo called Short transient receptor potential channel 5 or transient receptor protein 5 is a multi-pass membrane protein and is thought to form a receptor-activated non-selective calcium permeant cation channel. The protein is active alone or as a heteromultimeric assembly with TRPC1, TRPC3, and TRPC4. TRPC5 has been implicated in the mechanism of mercury toxicity and neurological behavior
Gene:
TRPC5
Human Protein:
UniProt Q9UL62
Tissue:
Brain, adult heart, testis, ovaries
Function/ Application:
Pressure sensing, TRPC5 counteracts TRPC1 in regulating neurite outgrowth and appears to be involved in growth cone collapse that occurs when the growth cone detects a repellant factor
Pathology:
Hypertrophic Pyloric Stenosis
Interaction:
TRPC1, TRPC3, TRPC4, calmodulin, CABP1, enkurin, Na+–H exchange regulatory factor, interferon-induced GTP-binding protein, ring finger protein 24, SEC14 domain and spectrin repeat-containing protein 1, Calcium channel, voltage-dependent, gamma subunit, Mitochondrial calcium uniporter 3
Modulator:
Thioredoxin
Assays:
Patch Clamp: whole cell
Particularities:
Ligand-gated ion channel, as well as mechano-sensitive ion channel

Data and Applications
TRPC5 - Block by Gadolinium
Patchliner data and applications:
Data are taken from Milligan C.J. et al., Nature Protocols, 2009, 4(2), 244-255.
Current voltage relationships showing activaion of TRPC5 by extracellular application of Gd3+ (100 μM). Voltage ramps (−100 mV to 100 mV, holding potential 0 mV) were for 1s at 0.1 Hz.
