Animal Trp proteins contain a transient receptor ion channel (IPR013555), typically located at the C-terminus of the ankyrin repeat sequence (IPR002110). Substantial evidence suggests that G protein-coupled receptors activate Trp proteins as structural components of calcium ion entry channels. A lot of different bodily functions depend on TRP channels. These include sensory functions like pheromone signaling, taste transduction, nociception, and temperature sensation; they also play a role in homeostatic functions like reabsorption of Ca2+ and Mg2+ and osmotic regulation. Additionally, they are involved in numerous motor functions, including muscle contraction and vasomotor control.
