Transient receptor potential canonical 1 (TRPC1) is a protein that in humans is encoded by the TRPC1 gene. [5] [6]

Contents

Function

TRPC1 is an ion channel located on the plasma membrane of numerous human and animal cell types. [7] It is a nonspecific cation channel, which means that both sodium and calcium ions can pass through it. TRPC1 is thought to mediate calcium entry in response to depletion of endoplasmic calcium stores or activation of receptors coupled to the phospholipase C system. In HEK293 cells the unitary current-voltage relationship of endogenous TRPC1 channels is almost linear, with a slope conductance of about 17 pS. The extrapolated reversal potential of TRPC1 channels is +30 mV. [8] The TRPC1 protein is widely expressed throughout the mammalian brain and has a similar corticolimbic expression pattern as TRPC4 and TRPC5. [9] [10] The highest density of TRPC1 protein is found in the lateral septum, an area with dense TRPC4 expression, and hippocampus and prefrontal cortex, areas with dense TRPC5 expression. [10]

History

TRPC1 was the first mammalian Transient Receptor Potential channel to be identified. In 1995 it was cloned when the research groups headed by Craig Montell and Lutz Birnbaumer were searching for proteins similar to the TRP channel in Drosophila . Together with TRPC3 they became the founding members of the TRPC ion channel family. [5] [6]

Transient receptor potential channels are a group of ion channels located mostly on the plasma membrane of numerous animal cell types. Most of these are grouped into two broad groups: Group 1 includes TRPC, TRPV, TRPVL, TRPM, TRPS, TRPN, and TRPA. Group 2 consists of TRPP and TRPML. Other less-well categorized TRP channels exist, including yeast channels and a number of Group 1 and Group 2 channels present in non-animals. Many of these channels mediate a variety of sensations such as pain, temperature, different kinds of tastes, pressure, and vision. In the body, some TRP channels are thought to behave like microscopic thermometers and used in animals to sense hot or cold. Some TRP channels are activated by molecules found in spices like garlic (allicin), chili pepper (capsaicin), wasabi ; others are activated by menthol, camphor, peppermint, and cooling agents; yet others are activated by molecules found in cannabis or stevia. Some act as sensors of osmotic pressure, volume, stretch, and vibration. Most of the channels are activated or inhibited by signaling lipids and contribute to a family of lipid-gated ion channels.

These are diacylgylcerol-sensitive cation channels known regulate intracellular calcium via activation of the phospholipase C (PLC) pathway and/or by sensing Ca2+ store depletion. Together, their role in calcium homeostasis has made them potential therapeutic targets for a variety of central and peripheral pathologies.

The transient receptor potential Ca2+ channel (TRP-CC) family (TC# 1.A.4) is a member of the voltage-gated ion channel (VIC) superfamily and consists of cation channels conserved from worms to humans. The TRP-CC family also consists of seven subfamilies (TRPC, TRPV, TRPM, TRPN, TRPA, TRPP, and TRPML) based on their amino acid sequence homology:

  1. the canonical or classic TRPs,
  2. the vanilloid receptor TRPs,
  3. the melastatin or long TRPs,
  4. ankyrin (whose only member is the transmembrane protein 1 [TRPA1])
  5. TRPN after the nonmechanoreceptor potential C (nonpC), and the more distant cousins,
  6. the polycystins
  7. and mucolipins.
