Summary: Enables mechanosensitive monoatomic cation channel activity. Contributes to calcium channel activity. Involved in several processes, including detection of mechanical stimulus involved in sensory perception; negative gravitaxis; and startle response. Part of calcium channel complex. Is active in plasma membrane. Is expressed in several structures, including adult antennal lobe local neurons; chordotonal neurons; longitudinal vein; organism subdivision; and sense organ. Human ortholog(s) of this gene implicated in several diseases, including Charcot-Marie-Tooth disease axonal type 2C; keratosis (multiple); migraine (multiple); motor neuron disease (multiple); and osteochondrodysplasia (multiple). Orthologous to several human genes including TRPV3 (transient receptor potential cation channel subfamily V member 3); TRPV5 (transient receptor potential cation channel subfamily V member 5); and TRPV6 (transient receptor potential cation channel subfamily V member 6).

Nanchung and Inactive define pore properties of the native auditory transduction channel in Drosophila.
Title: Nanchung and Inactive define pore properties of the native auditory transduction channel in Drosophila.
The transient receptor potential channels NOMPC, NANCHUNG, and INACTIVE, but not the dmPIEZO channel, are implicated in mechanotransduction and/or signal amplification for the detection of sound by the larval Cho neurons.
Title: Sound response mediated by the TRP channels NOMPC, NANCHUNG, and INACTIVE in chordotonal organs of Drosophila larvae.
identification of two Drosophila melanogaster transient receptor potential channels needed for sensing humidity: water witch (wtrw), which is required to detect moist air, and nanchung (nan), which is involved in detecting dry air
Title: Drosophila hygrosensation requires the TRP channels water witch and nanchung.
Nan mediates hypo-osmotically activated calcium influx and cation currents; expressed in vivo exclusively in chordotonal neurons and localized to their sensory cilia; essential component of the chordotonal mechanotransducer
Title: A TRPV family ion channel required for hearing in Drosophila.
