The oncogene v-myb and its cellular progenitor c-myb encode nuclear, DNA binding phosphoproteins that are thought to regulate the expression of myb-responsive genes during myeloid differentiation. To identify such myb-regulated genes, and to explore the mechanisms by which v-myb affects their expression, we have established a conditional expression system for v-myb. We have converted the v-myb protein to an estrogen-inducible transactivator by fusing the protein to the hormone binding domain of the human estrogen receptor. Expression of the chimeric protein in a chicken macrophage cell-line causes estrogen-dependent, reversible changes in the differentiation state as well as alterations in the gene expression program of the cells. We have used this estrogen-dependent v-myb expression system to identify a novel v-myb regulated gene.
