[Representatives of the seven TRP subfamilies]
The seven TRP subfamilies. Representatives of the different subfamilies are indicated at the top and bottom, respectively. Several domains are indicated: ankyrin repeats (A), coiled coil domain (cc), protein kinase domain (TRPM6/7 only), transmembrane segments, and the TRP domain (1) TRP proteins are supposed to form 6 membrane-spanning segments whereas the pore region is formed by a hydrophilic region between S5 and S6 forms. The N- and C-termini are located intracellularly. The N-terminus often contains ankyrin repeats as well as a coiled-coil domain, which are suspected to bind with other proteins or the cytoskeleton. Especially they are thought to be needed for TRP protein interaction because a functional channel contains 4 TRP subunits, either similar or different ones, to form homo- or heteromers (4,5).
