The MtnC ATG start codon and several neighbouring amino acids have been replaced by a NotI site.
MtnDOreR, MtnDOreR, MtnCΔATG, MtnCΔATG, MtnBΔATG, MtnBΔATG, MtnAΔATG, MtnAΔATG is an enhancer of partially lethal - majority die phenotype of MTF-1Δ580-791.tub

The wing defects seen in flies expressing MTF-1Δ580-791.tub or MTF-1Δ761-791.tub are enhanced by the "qMtn" mutant combination (MtnAΔATG MtnBΔATG MtnCΔATG MtnDOreR) and the mutant flies show a very low eclosion rate.
MtnAΔATG MtnBΔATG MtnCΔATG MtnDOreR quadruple mutants show little or no survival on 1mM copper or 100mM cadmium concentrations in food compared to controls.
MtnAΔATG MtnBΔATG MtnCΔATG MtnDΔATG quadruple mutants show little or no survival on 1mM copper or 100mM cadmium concentrations in food compared to controls.
MtnAΔATG MtnBΔATG MtnCΔATG MtnDOreR quadruple mutants are viable and fertile, but are highly sensitive to copper and cadmium load in food, showing no survival on 0.5mM copper or 50μM cadmium concentrations. The quadruple mutants are not sensitive to copper depletion.
With normal food, the life span of MtnAΔATG MtnBΔATG MtnCΔATG MtnDOreR quadruple homozygotes is similar to that of controls. However, at 50μM copper, the mean life span of quadruple homozygous males is 6 days shorter than that of controls, and at 75μM copper, the mean life span of quadruple homozygous males is 14 days shorter than that of controls. The mean life span of quadruple homozygous females is 3 days shorter than that of controls at both 50μM and 75μM copper.
