Drives expression in calcium-sensing neuron of labellar S-type taste bristles, and in a subset of leg taste bristle chemosensory neurons that project into the adult ventral nerve cord; and in gustatory receptor neurons of the terminal organ in larvae.
Scer\GAL4ppk23.2.695 drives expression in 10 neurons that innervate the terminal organ, and in one internal sensory neuron located along the larval pharynx.
ScerGAL4ppk23.2.695 drives expression in gustatory receptor neurons in the proboscis and in the legs. These neurons labeled with ScerGAL4ppk23.2.695 do not overlap with expression of ScerGAL4ppk28.PC, which labels the water-sensing neurons, ScerGAL4Gr64f.9.7 which labels the sugar-responsive neurons,or with candidate pheromone receptor ScerGAL4Gr32a.3.776. A few positive ScerGAL4ppk23.2.695 neurons in the proboscis co-express AvicGFPGr66a.3x.IRES.2x which labels bitter-responsive neurons, but there is no co-expression in the leg sensory neurons. Expression of ScerGAL4ppk23.2.695 in the legs marks more than one cell per bristle and it overlaps with that of fruP1.LexA.
There is sexual dimorphism in the leg gustatory receptor neurons labeled by ScerGAL4ppk23.2.695 : twice as many cells are labeled in males compared to females and the neuronal projections of males in the prothoracic ganglion cross the midline whereas female ones do not.
Inactivation of a subset of Scer\GAL4ppk23.2.695 cells (using Ctet\tetXTNT-LC.FRT.stop.UAS and Scer\FLP1335) in males has little effect on the frequency of successful matings, copulation duration or copulation latency, compared to controls.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 30[o]C) of a subset of Scer\GAL4ppk23.2.695 cells (activation restricted using Ecol\lexAVGlut-MI04979-TlexA:QFAD.2 and Scer\GAL80ts.lexAop.cTa) in adult males significantly decreases wing extensions towards females, compared to controls.
When males flies in which the Scer\GAL4ppk23.2.695-expressing neurons have been silenced are exposed to other males that have been engineered to produce female pheromones (by expressing traScer\UAS.cFa under the control of Scer\GAL4OK72) they do not show the increase in starvation resistance seen when they are exposed to wild type males.
Activation of Scer\GAL4ppk23.2.695-expressing neurons in wild type males results in reductions in starvation resistance, triacylglyceride (TAG) amount and lifespan compared with wild type males. Activity levels, respiration rate and feeding are unaffected.
Inhibition (using Ctet\TeTxLCTNT.UAS) of Scer\GAL4ppk23.2.695 cells significantly reduces the preference of larvae for larval-treated substrate, compared to controls; attraction to the secreted larval fatty acids (Z)-5-tetradecanoic acid and (Z)-7-tetradecanoic acid is significantly reduced, compared to controls.
