-== Publication Abstract from PubMed ==
-Chromosomal translocations of MLL1 (Mixed Lineage Leukemia 1) yield oncogenic chimeric proteins containing the N-terminal portion of MLL1 fused with distinct partners. The MLL1-AF10 fusion causes leukemia through recruiting the H3K79 histone methyltransferase DOT1L via AF10's octapeptide and leucine zipper (OM-LZ) motifs. Yet, the precise interaction sites in DOT1L, detailed interaction modes between AF10 and DOT1L, and the functional configuration of MLL1-AF10 in leukeomogenesis remain unknown. Through a combined approach of structural and functional analyses, we found that the LZ domain of AF10 interacts with the coiled-coil domains of DOT1L through a conserved binding mode and discovered that the C-terminal end of the LZ domain and the OM domain of AF10 mediate the formation of a DOT1L-AF10 octamer via tetramerization of the binary complex. We reveal that the oligomerization ability of the DOT1L-AF10 complex is essential for MLL1-AF10's leukemogenic function. These findings provide insights into the molecular basis of pathogenesis by MLL1 rearrangements.
-A higher-order configuration of the heterodimeric DOT1L-AF10 coiled-coil domains potentiates their leukemogenenic activity.,Song X, Yang L, Wang M, Gu Y, Ye B, Fan Z, Xu RM, Yang N Proc Natl Acad Sci U S A. 2019 Sep 16. pii: 1904672116. doi:, 10.1073/pnas.1904672116.
