UASp regulatory sequences drive expression of kel that contains mutations in both of the predicted surface exposed Lys residues (amino acid replacements K414R and K428R).
kelK414R.K428R.UASp/Scer\GAL4VP16.mat.αTub67C rescues kelDE1
kelK414R.K428R.UASp/Scer\GAL4VP16.otu rescues kelDE1
Expression of kelK414R.K428R.Scer\UAS.P\T under the control of either Scer\GAL4mat.αTub67C.T:Hsim\VP16 or Scer\GAL4otu.T:Hsim\VP16 rescues the female sterility of kelDE1 mutants.
