NheI-XhoI genomic fragment from 2.5kb upstream to 1.2kb downstream of the TrpA1 open reading frame.
Expression of TrpA1+tHa rescues the uracil-dependent defecation defect seen in TrpA1ins flies.
TrpA1+tHa rescues the thermal avoidance defect found in TrpA1ins mutant flies.
The altered distribution along a thermal gradient that is seen in Dp(3;3)TrpA1ins flies is rescued by TrpA1+tHa.
