UAS regulatory sequences drive expression of a mutant form of Myb in which the SPS amino acid sequence starting at position 389 has been replaced with AA. The construct is tagged at the N-terminus with EGFP.
Expression of MybSPS389.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4da.G32 partially rescues MybMH107 mutant lethality at 25[o]C, resulting in approximately 85% of the number of adult flies seen in wild type.
