Breakpoint(s) molecularly mapped
Proximal breakpoint between +49 and +50.5 kb; distal breakpoint between +72.5 and +77.8 kb (DNA walk of Bender, Spierer and Hogness, 1983, J. Mol. Biol. 168: 17-33).
Suppresses the position effect variegation at the w locus caused by In(1)wm4 and Dp(3;Y)BL2, the position effect variegation at the bw locus caused by In(2R)bwVDe2 and Dp(?;2)bwD and the position effect variegation at the y locus caused by Dp(1;f)1187.
Heterozygotes show a suppression of the position effect variegation seen in In(1)wm4. This phenotype is dominanted by the Y dependent enhancer of PEV effect.
Suppresses the position effect variegation at the w locus seen in the insertion lines P{hsp26-pt-T}118E-10, P{hsp26-pt-T}39C-12 and P{hsp26-pt-T}Dyrk3118E-15, but has no effect on the position effect variegation at the w locus seen in the insertion line P{hsp26-pt-T}39C-5.
Homozygotes are embryonic lethal and have no CNS-specific Ace enzyme.
does not fully remove Ace activity, but behaves as recessive Ace lethal.
