A tubulin promoter drives expression of a truncated form of MTF-1 (amino acid residues 1-760).
Flies expressing MTF-1Δ761-791.tub eclose at a rate approaching that of wild type and have notched wings.
The median lifespan of flies expressing MTF-1Δ761-791.tub is reduced to a median of 28 days (compared to a median lifespan of 49 days for wild-type controls).
The wing defects seen in flies expressing 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.
