Insertion within an intron located between two coding exons, in the appropriate predicted reading frame to fuse the GFP exon in the inserted construct to the endogenous protein.
Male and female mutant flies show substantially increased survival after exposure to alcohol vapour compared to wild type. Fewer of the mutant flies show blackening of the third antennal segment after exposure to alcohol vapour compared to wild type.
Homozygotes become sedated more rapidly than control flies after exposure to ethanol.
