 1-329 1.98e-167

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).

 1-329 1.98e-167

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. (McCleskey and Gold, 1999). [Transport and binding proteins, Cations and iron carrying compounds]

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.

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.

 81-219 3.66e-10

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).

 81-219 4.26e-10

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.

 82-216 3.19e-08

Transient Receptor Potential channel, Vanilloid subfamily (TRPV), types 5 and 6; TRPV5 and TRPV6 (TRPV5/6) are two homologous members within the vanilloid subfamily of the transient receptor potential (TRP) family. TRPV5 and TRPV6 show only 30-40% homology with other members of the TRP family and have unique properties that differentiates them from other TRP channels. They mediate calcium uptake in epithelia and their expression is dramatically increased in numerous types of cancer. The structure of TRPV5/6 shows the typical topology features of all TRP family members, such as six transmembrane regions, a short hydrophobic stretch between transmembrane segments 5 and 6, which is predicted to form the Ca2+ pore, and large intracellular N- and C-terminal domains. The N-terminal domain of TRPV5/6 contains three ankyrin repeats. This structural element is present in several proteins and plays a role in protein-protein interactions. The N- and C-terminal tails of TRPV5/6 each contain an internal PDZ motif which can function as part of a molecular scaffold via interaction with PDZ-domain containing proteins. A major difference between the properties of TRPV5 and TRPV6 is in their tissue distribution: TRPV5 is predominantly expressed in the distal convoluted tubules (DCT) and connecting tubules (CNT) of the kidney, with limited expression in extrarenal tissues. In contrast, TRPV6 has a broader expression pattern such as expression in the intestine, kidney, placenta, epididymis, exocrine tissues, and a few other tissues.

Transient Receptor Potential channel, Vanilloid subfamily (TRPV), types 1-4; TRPV1-4 are thermo-sensing channels that function directly in temperature-sensing and nociception; they share substantial structural and functional properties. Transient Receptor Potential (TRP) ion channels activated by temperature (thermo TRPs) are important molecular players in acute, inflammatory, and chronic pain states. So far, 11 TRP channels in mammalian cells have been identified as thermosensitive TRP (thermo-TRP) channels. TRPV1-4 channels are activated by different heat temperatures, for example, TRPV1 and TRPV2 are activated by high temperatures (>43C and >55C, respectively). TRPV1-4 belong to the vanilloid TRP subfamily (TRPV), named after the founding member vanilloid receptor 1 (TRPV1). The structure of TRPV shows the typical topology features of all 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.

 92-222 5.33e-06

Transient Receptor Potential channel, Vanilloid subfamily (TRPV), type 3; TRPV3 is a temperature-sensitive Transient Receptor Potential (TRP) ion channel that is activated by warm temperatures, synthetic small-molecule chemicals, and natural compounds from plants. TRPV3 function is regulated by physiological factors such as extracellular divalent cations and acidic pH, intracellular adenosine triphosphate, membrane voltage, and arachidonic acid. It is expressed in both neuronal and non-neuronal tissues including epidermal keratinocytes, epithelial cells in the gut, endothelial cells in blood vessels, and neurons in dorsal root ganglia and CNS. TRPV3 null mice have abnormal hair morphogenesis and compromised skin barrier function. It may play roles in inflammatory skin disorders, such as itch and pain sensation. TRPV3 is also expressed by many neuronal and non-neuronal tissues, showing that TRPV3 might play roles in other unknown cellular and physiological functions. TRPV3 belongs to the vanilloid TRP subfamily (TRPV), named after the founding member vanilloid receptor 1 (TRPV1). The structure of TRPV shows the typical topology features of all 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.

Transient Receptor Potential channel, Vanilloid subfamily (TRPV), type 4; TRPV4 is expressed broadly in neuronal and non-neuronal cells. It is activated by various stimuli, including hypo-osmolarity, warm temperature, and chemical ligands. TRPV4 acts in physiological functions such as osmoregulation and thermoregulation. It also has a role in mechanosensation in the vascular endothelium and urinary tract, and in cell barrier formation in vascular and epidermal tissues. Knockout mice studies suggested the functional importance of TRPV4 in the central nervous system, nociception, and bone formation. TRPV4 belongs to the vanilloid TRP subfamily (TRPV), named after the founding member vanilloid receptor 1 (TRPV1). 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.

Transient Receptor Potential channel, Vanilloid subfamily (TRPV), type 2; TRPV2 is closely related to TRPV1, sharing high sequence identity (>50%), but TRPV2 shows a higher temperature threshold and sensitivity for activation than TRPV1. TRPV2 can be stimulated by ligands or lipids, and is involved in osmosensation and mechanosensation. TRPV2 is expressed in both neuronal and non-neuronal tissues, and it has been implicated in diverse physiological and pathophysiological processes, including cardiac-structure maintenance, innate immunity, and cancer. TRPV2 belongs to the vanilloid TRP subfamily (TRPV), named after the founding member vanilloid receptor 1 (TRPV1). 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.
