Turning on a dimer: new insights into MLL chimeras

Cancer Cell. 2003 Aug;4(2):81-3. doi: 10.1016/s1535-6108(03)00192-2.

Abstract

In this issue of Cancer Cell, demonstrate a novel mechanism for the oncogenic activity of MLL chimeric proteins. By providing coiled-coil or other dimerization domains, the cytoplasmic partners of MLL fusion proteins donate a platform for MLL homodimerization, allowing recruitment of accessory factors needed to activate the critical downstream targets, including selected subsets of the major HOX genes.
