Amino acids 705 to 1039 are driven by the hsp70 promoter.
There is a complete loss of male viability in homozygous mutants where expression of msl-1C.hs.T:Zzzz\FLAG in induced by heatshock. There is a partial loss of male viability (about 2/5 of expected males survive) in heterozygous mutants where expression of msl-1Δ84.T:Zzzz\FLAG in induced by milder heatshock. The addition of msl-1γ269 has no significant affect on the loss of male viability.
msl-1C.hs.Tag:FLAG has phenotype, non-enhanceable by mle13
msl-1C.hs.Tag:FLAG has phenotype, non-enhanceable by msl-2γ136
msl-1C.hs.Tag:FLAG has phenotype, non-enhanceable by msl-31
msl-1C.hs.Tag:FLAG has phenotype, non-suppressible by mle13
msl-1C.hs.Tag:FLAG has phenotype, non-suppressible by msl-2γ136
msl-1C.hs.Tag:FLAG has phenotype, non-suppressible by msl-31
mle13, msl-2γ136 or msl-31 have no significant affect on the loss of male viability seen in flies expressing msl-1Δ84.T:Zzzz\FLAG.
