Abstract: Mixed Lineage Leukemia 1 (MLL1), an important member of Histone Methyltransferases
(HMT) family, is capable of catalyzing mono-, di-, and trimethylation of Histone 3 lysine 4 (H3K4).
The optimal catalytic activity of MLL1 requires the formation of a core complex consisting of
MLL1, WDR5, RbBP5, and ASH2L. The Protein-Protein Interaction (PPI) between WDR5 and
MLL1 plays an important role in abnormal gene expression during tumorigenesis, and disturbing
this interaction may have a potential for the treatment of leukemia harboring MLL1 fusion proteins.
In this review, we will summarize recent progress in the development of inhibitors targeting MLL1-
WDR5 interaction.
