tetramerization domain of TRPM; TRPM7_tetra is a short anti-parallel coiled-coil tetramerization domain of the transient receptor potential cation channel subfamily M member proteins 1-8. It is held together by extensive core packing and interstrand polar interactions. Transient receptor potential (TRP) channels comprise a large family of tetrameric cation-selective ion channels that respond to diverse forms of sensory input. The presence of cytoplasmic domains that direct channel assembly appears to be a feature of many voltage-gated ion channel superfamily members. : Pssm-ID: 465156 Cd Length: 56 Bit Score: 84.69 E-value: 6.43e-20

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 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 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.
