UASt regulatory sequences drive expression of an inverted repeat.
Expression of TbhKK102670 under the control of Scer\GAL4dimm-929 does not affect sensitivity to (S,Z,Z)-CH503 (a more potent stereoisomer of the gustatory sex pheromone CH503). As in wild type flies, courtship defects are seen in response to (S,Z,Z)-CH503.
