The potential implications of these findings for the leukemogenesis by MLL-ENL are discussed..     ///    MLL-ENL strongly transactivated several unrelated promoters including the promoter of Hoxa7 a potential target gene for the unaltered MLL protein.     ///    Whereas potential functions have been suggested for isolated domains of either MLL or ENL no experimental data exist for the biological properties of the complete chimeric MLL-ENL protein.
