the Akap200 locus, and (iii) several different Gal4 transgenes, all marked with mini-w in the same w1118 genetic background. Expression of mini-w from these transposon insertions strongly correlated with ethanol sensitivity in eRING assays (Figure 1A), but not with internal ethanol concentration, expression of TGFβR or Akap200 mRNA, or negative geotaxis in the absence of ethanol (not shown). These results suggest that expression of mini-w influences sensitivity to ethanol in the eRING paradigm.
