Question 5

Drosophila NompC is a mechanotransduction channel subunit for gentle touch sensation

Answer 5

Yan et al, 2013

Question 6

Direct gating and mechanical integrity of Drosophila auditory transducers require TRPN1 (NompC)

Answer 6

Effertz et al, 2012

Question 7

NompC TRP channel essential for Drosophila sound receptor function - remnant nerve potentials associate with gravity/wind

Answer 7

Effertz et al (2011)

Answer 8

Montealegre et al (2012)

Question 9

Counter to Montealegre: convergent evolution matches physical requirements of hearing on land
