UASp sequences regulate expression of a mutant Mer cDNA that carries a M177I amino acid substitution. The coding sequence is tagged at the N-terminal end with Tag:MYC.
Scer\GAL4Act5C.PU/Mer3.UASp.Tag:MYC partially rescues Mer4
Expression of MerScer\UAS.P\T.T:Hsap\MYC under the control of Scer\GAL4Act5C rescues the lethality but not the infertility phenotype of Mer4 males.
