Vertebrate myb genes encode DNA-binding proteins that regulate transcription and have been implicated in regulation of cell proliferation, differentiation, and apoptosis. We have demonstrated that the single myb gene in Drosophila melanogaster, Dm myb, is required for the G(2)/M transition of the cell cycle and for suppression of endoreduplication. Recently, it has become apparent that the family of proteins containing Myb-related DNA-binding domains is much larger than originally believed and that the biochemical properties and functions of these proteins are diverse. We undertook studies to characterize the biochemical properties of the Drosophila Myb protein (DMyb). We now provide evidence that in addition to having homology with the vertebrate Myb proteins, the Drosophila Myb protein (DMyb) shares its biochemical properties. DMyb binds to a similar consensus sequence and activates transcription from a reporter construct regulated by vertebrate Myb proteins. We also show that DMyb proteins carrying mutations corresponding to previously isolated mutant alleles of Dm myb are less active as transcriptional activators than wild-type DMyb, indicating that a decrease in transcriptional activation ability is likely to cause the mutant phenotypes.
