TRPV4 also known as transient receptor potential vanilloid 4 is an ion channel protein that plays a mechanical role in the human body. This protein with a mass of approximately 98 kDa is sensitive to osmotic pressure mechanical forces and temperature changes. It acts as a calcium-permeable non-selective cation channel. TRPV4 is widely expressed in various tissues including the choroid plexus as well as in the epithelial cells endothelium and certain neurons. The expression pattern suggests its involvement in various physiological processes.

Biological function summary

TRPV4 serves functions essential for osmoregulation mechanosensation and thermosensation. It often forms a complex with other proteins to modulate calcium influx which influences cellular responses. TRPV4 impacts various biological processes such as maintaining cell volume and adapting to temperature changes. Its role in regulating fluid movement across barriers like those in the choroid plexus demonstrates its involvement in maintaining homeostasis. These interactions highlight the protein's widespread influence on various cellular functions.

Pathways

TRPV4 integrates into critical signal transduction pathways that include the mechanotransduction and osmoregulation pathways. It is closely related to other TRP family members such as TRPV1 and TRPC1 within these pathways. The mechanotransduction pathway allows it to convey mechanical stimuli into electrochemical activity impacting various systems throughout the body. The osmoregulation pathway highlights its ability to sense and respond to osmotic shifts maintaining cellular and systemic equilibrium.

TRPV4 has significant links to a range of pathologies such as skeletal dysplasias and neuropathies. Mutations in TRPV4 can lead to altered channel function contributing to conditions like Charcot-Marie-Tooth disease and congenital distal spinal muscular atrophy. These associations often involve the misregulation of calcium homeostasis where TRPV4's interaction with proteins like TRPV1 leads to a disruption of normal cellular processes highlighting the importance of maintaining TRPV4's proper function to prevent those diseases.
