DNA-binding protein that specifically recognizes the sequence 5'-YAAC[GT]G-3'. The Myb-Ets protein induces predominantly erythroblastosis in chicken and transforms avian erythroblasts and immature myelomonocytic cells in culture. It appears that the Ets domain is responsible for the effects on erythroid cells and that the Myb domain encodes the myeloid-transforming capacity
