P{lArB} insertion 183bp upstream of the putative transcription start site.
Enhancer trap element inserted into intron of east.
The eastETX3 phenotype is not associated with a significant rate of nondisjunction of achiasmate X-chromosomes in female meiosis.
Homozygotes or hemizygotes show mutant response to benzaldehyde and isoamylacetate, ethylacetate, propionic acid and butanol in olfactory jump test, and Y maze assay. Also show specific gustatory defects, being more tolerant to high salts than wild type. Phototactic responses of adults as measured in countercurrent tests are normal.
Mutant in response to salts.
