Transient Receptor Potential channel, Vanilloid subfamily (TRPV); The vanilloid TRP subfamily (TRPV), named after the vanilloid receptor 1 (TRPV1), consists of six members: four thermo-sensing channels (TRPV1, TRPV2, TRPV3, and TRPV4) and two Ca2+ selective channels (TRPV5 and TRPV6). The calcium-selective channels TRPV5 and TRPV6 can be heterotetramers and are important for general Ca2+ homeostasis. All four channels within the TRPV1-4 group show temperature-invoked currents when expressed in heterologous cell systems, ranging from activation at ~25C for TRPV4 to ~52C for TRPV2. The structure of TRPV shows the typical topology features of all Transient Receptor Potential (TRP) ion channel family members, such as six transmembrane regions, a short hydrophobic stretch between transmembrane segments 5 and 6 and large intracellular N- and C-terminal domains. The TRP family consists of membrane proteins that function as ion channels that communicate between the cell and its environment, by a vast array of physical or chemical stimuli, including radiation (in the form of temperature, infrared ,or light) and pressure (osmotic or mechanical). TRP channels are formed by a tetrameric complex of channel subunits. Based on sequence identity, the mammalian TRP channel family is classified into six subfamilies, with significant sequence similarity within the transmembrane domains, but very low similarity in their N- and C-terminal cytoplasmic regions. The six subfamilies are named based on their first member: TRPC (canonical), TRPV (vanilloid), TRPM (melastatin), TRPA (ankyrin), TRPML (mucolipin), and TRPP (polycystic).

transient-receptor-potential calcium channel protein; The Transient Receptor Potential Ca2+ Channel (TRP-CC) Family (TC. 1.A.4)The TRP-CC family has also been called the store-operated calcium channel (SOC) family. The prototypical members include the Drosophila retinal proteinsTRP and TRPL (Montell and Rubin, 1989; Hardie and Minke, 1993). SOC members of the family mediate the entry of extracellular Ca2+ into cells in responseto depletion of intracellular Ca2+ stores (Clapham, 1996) and agonist stimulated production of inositol-1,4,5 trisphosphate (IP3). One member of the TRP-CCfamily, mammalian Htrp3, has been shown to form a tight complex with the IP3 receptor (TC #1.A.3.2.1). This interaction is apparently required for IP3 tostimulate Ca2+ release via Htrp3. The vanilloid receptor subtype 1 (VR1), which is the receptor for capsaicin (the ?hot? ingredient in chili peppers) and servesas a heat-activated ion channel in the pain pathway (Caterina et al., 1997), is also a member of this family. The stretch-inhibitable non-selective cation channel(SIC) is identical to the vanilloid receptor throughout all of its first 700 residues, but it exhibits a different sequence in its last 100 residues. VR1 and SICtransport monovalent cations as well as Ca2+. VR1 is about 10x more permeable to Ca2+ than to monovalent ions. Ca2+ overload probably causes cell deathafter chronic exposure to capsaicin.

Transient receptor ion channel II; This domain is found in the transient receptor ion channel (Trp) family of proteins. There is strong evidence that Trp proteins are structural elements of calcium-ion entry channels activated by G protein-coupled receptors. This domain does not tend to appear with the TRP domain (pfam06011) but is often found to the C-terminus of Ankyrin repeats (pfam00023).

Transient Receptor Potential channel, Vanilloid subfamily (TRPV), type 1; Vanilloid receptor 1 (TRPV1), a capsaicin (vanilloid) receptor, is the founding member of the vanilloid TRP subfamily (TRPV). In humans, it is expressed in the brain, kidney, pancreas, testis, uterus, spleen, stomach, small intestine, lung and liver. TRPV1 has been implicated to have function in thermo-sensation (heat), autonomic thermoregulation, nociception, food intake regulation, and multiple functions in the gastrointestinal (GI) tract. The receptor has also been involved in growth cone guidance, long-term depression, endocannabinoid signaling and osmosensing in the central nervous system. TRPV1 is up regulated in several human pathological conditions including vulvodynia, GI inflammation, Crohn's disease and ulcerative colitis. TRPV1 knock-out mice exhibit impaired sensation to thermal-mechanical acute pain. The structure of TRPV shows the typical topology features of all Transient Receptor Potential (TRP) ion channel family members, such as six transmembrane regions, a short hydrophobic stretch between transmembrane segments 5 and 6 and large intracellular N- and C-terminal domains.

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.
