## TRPV1 Protein is a protein. This page describes its structure, normal nervous system function, role in neurodegenerative disease, and potential as a therapeutic target.
TRPV1 (Transient Receptor Potential Vanilloid 1) is a non-selective cation channel belonging to the TRP (Transient Receptor Potential) channel superfamily. The channel is a tetramer composed of four identical subunits, each containing six transmembrane domains (S1-S6) with a pore-forming loop between S5 and S6[1]. The N-terminus contains ankyrin repeat domains (ARD) that are involved in protein-protein interactions and channel regulation[2].
Key structural features:
TRPV1 is expressed in sensory neurons (dorsal root ganglion, trigeminal ganglion), where it functions as a polymodal nociceptor activated by[3]:
In the central nervous system, TRPV1 is expressed in:
Physiological functions include:
TRPV1 dysregulation is implicated in several neurodegenerative diseases[4][5]:
TRPV1 is a validated drug target for pain management, with implications for neurodegenerative diseases[6]:
