Transient receptor potential cation channel subfamily V member 4 (TRPV4)

Non-selective calcium permeant cation channel involved in osmotic sensitivity and mechanosensitivity. Also activated by heat, low pH, citrate and phorbol esters (PubMed:16293632, PubMed:18826956, PubMed:18695040, PubMed:25256292, PubMed:20037586, PubMed:21964574).

Increase of intracellular Ca(2+) potentiates currents. Channel activity appears to be controlled by a calmodulin-dependent mechanism using a negative feedback mechanism (PubMed:12724311, PubMed:18826956).
