Trpv4 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
TRPV4 (Transient Receptor Potential Vanilloid 4) is a member of the TRPV subfamily of polymodal cation channels. Encoded by the TRPV4 gene, this channel integrates multiple physical and chemical stimuli to regulate calcium homeostasis and cellular signaling in the nervous system [1][2].
TRPV4 is notable for its ability to respond to diverse stimuli including mechanical force, temperature, osmotic pressure, and chemical effectors. This polymodality makes it uniquely positioned to sense and respond to environmental changes in both physiological and pathological contexts [3].
TRPV4 forms a tetrameric channel with each subunit comprising:
Ankyrin Repeat Domain (ARD)
Voltage Sensor-Like Domain (VSLD)
Pore Domain
TRPV4 is regulated by:
