3228bp genomic fragment spanning the entire lush transcription unit, extending from 958bp upstream of the start codon to 1693bp downstream of the stop codon.
lush+tGa, lushF121A.tGa, lushD118A.tGa and lushF121W.tGa each restore the sensitivity of Or67d-expressing neurons to cis-vaccenyl acetate (cVA) in lush1 mutants. The neuronal response across a 10,0000-fold range of cVA concentrations is similar in all four cases, with the only statistically significant difference being observed at the highest cVA concentration (100%), where flies rescued with lushF121W.tGa or with lushD118A.tGa show a slightly lower cVA sensitivity than those rescued with lush+tGa.
lush+tGa, lushF121A.tGa, lushF121W.tGa and lushD118A.tGa each restore the spontaneous firing of Or67d-expressing neurons in lush1 mutants. There is no statistically significant difference in firing activity across the four genotypes.
