3228bp genomic fragment spanning the entire lush transcription unit, extending from 958bp upstream of the start codon to 1693bp downstream of the stop codon. The coding sequence has been mutated to carry a F121A amino acid replacement.
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.
