In this issue of Cell Chemical Biology, Zhang et al.1 report the identification of a high-affinity EMBOW-derived inhibitor of WDR5, Ac7, which demonstrates in-cell target engagement and in vivo antileukemic efficacy. The microprotein-inspired inhibitor potently blocks the WDR5-MLL1 interaction, suppressing H3K4 methylation and transcription of target genes in mixed lineage leukemia (MLL)-rearranged leukemia.
