Title: Ultrastructural organization of NompC in the mechanoreceptive organelle of Drosophila campaniform mechanoreceptors.
Drosophila food texture preference requires NOMPC, a TRP-family mechanosensory channel. NOMPC localizes to the sensory dendrites of neurons housed within gustatory sensilla, and is essential for their mechanosensory-evoked responses.

Title: Electron cryo-microscopy structure of the mechanotransduction channel NOMPC.
Study provides evidence that Ankyrin repeats are essential for NOMPC mechanogating; further mechanogating of NOMPC requires the integrity of microtubules associated to the plasma membrane, providing a precedent for a tethered mechanism for mechanotransduction channel activation.
Title: Ankyrin Repeats Convey Force to Gate the NOMPC Mechanotransduction Channel.
NOMPC is required for establishing the fine structure of the sensory dendritic compartment.
Title: NOMPC-dependent mechanotransduction shapes the dendrite of proprioceptive neurons.
NOMPC is likely to be a crucial component of mechanotransducers that accounts for mechanotransductions in mechanosensory neurons of Drosophila.
Title: NOMPC is likely a key component of Drosophila mechanotransduction channels.
This study provides strong evidence that the ankyrin-repeat domains of the transient receptor potential channel NOMPC structurally contribute to the membrane-microtubule connecting filaments in Drosophila.
Title: A NOMPC-dependent membrane-microtubule connector is a candidate for the gating spring in fly mechanoreceptors.
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.
Ripped Pocket (rpk), No Mechanoreceptor Potential C (nompC), and NMDA Receptors 1 and 2 (Nmdars) play critical roles in both behavioral responses to touch and in the formation of the actin-rich sensory filopodia.
Title: Dendritic filopodia, Ripped Pocket, NOMPC, and NMDARs contribute to the sense of touch in Drosophila larvae.
