NCIt definition : A fusion protein encoded by the MLL/CBL fusion gene. This protein is comprised of
the N-terminal half of the histone-lysine N-methyltransferase MLL protein, including
the AT hook DNA binding domain and the DNA methyltransferase domain, fused to the
C-terminal proline-rich region and ubiquitin-binding leucine zipper domain of the
E3 ubiquitin-protein ligase CBL protein.;
