TRPV4
Protein-coding gene in humans / From Wikipedia, the free encyclopedia
Transient receptor potential cation channel subfamily V member 4 is an ion channel protein that in humans is encoded by the TRPV4 gene.
The TRPV4 gene encodes TRPV4, initially named "vanilloid-receptor related osmotically activated channel" (VR-OAC) and "OSM9-like transient receptor potential channel, member 4 (OTRPC4)",[5][6] a member of the vanilloid subfamily in the transient receptor potential (TRP) superfamily of ion channels.[7][8][9] The encoded protein is a Ca2+-permeable, nonselective cation channel that has been found involved in multiple physiologic functions, dysfunctions and also disease. It functions in the regulation of systemic osmotic pressure by the brain, in vascular function, in liver, intestinal, renal and bladder function, in skin barrier function and response of the skin to ultraviolet-B radiation, in growth and structural integrity of the skeleton, in function of joints, in airway- and lung function, in retinal and inner ear function, and in pain. The channel is activated by osmotic, mechanical and chemical cues. It also responds to thermal changes (warmth). Channel activation can be sensitized by inflammation and injury.
The TRPV4 gene has been co-discovered by W. Liedtke et al.[5] and R. Strotmann et al.[6]
