Transient receptor potential cation channel subfamily V member 4 is a protein that in humans is encoded by the TRPV4 gene.[1][1][2][2][3]

This gene encodes TRPV4, a member of the OSM9-like transient receptor potential channel (OTRPC) subfamily in the transient receptor potential (TRP) superfamily of ion channels.[3][4][5] The encoded protein is a Ca2+-permeable, nonselective cation channel that is thought to be involved in the regulation of systemic osmotic pressure.[6] Two transcript variants encoding different isoforms have been found for this gene.[7]

Clinical significance[edit]

Mutations in the TRPV4 gene are associated with a range of disorders, including brachyolmia type 3, congenital distal spinal muscular atrophy, scapuloperoneal spinal muscular atrophy and subtype 2C of Charcot–Marie–Tooth disease.[8]


A number of TRPV4 agonists and antagonists have been identified in the past ten years.[9] The discovery of unselective modulators (e.g. antagonist Ruthenium Red) was followed by the apparition of more potent (agonist 4aPDD)[10] or selective (antagonist RN-1734)[11] compounds, including some with bioavailability suitable for in vivo pharmacology studies such as agonist GSK1016790A[12] (with ~10 fold selectivity vs TRPV1) and antagonist HC-067047[13] (with ~5 fold selectivity vs hERG and ~10 fold selectivity vs TRPM8).


TRPV4 has been shown to interact with MAP7[14] and LYN.[15]
