Here, we performed a CRISPR-tiling screen against known H3K4 methylation modifiers in an MLL-r AML model. Disrupting the SETD1B catalytic SET domain caused depletion of FLT3-ITD or Nras<sup>G12D</sup>-expressing AML cells, and gene expression downregulation, particularly in the MYC pathway. SETD1B SET domain loss results in a significant decrease in H3K4me3 breadth. Exogenous MYC expression or disrupting H3K4 demethylase KDM5C significantly restored growth defects in SETD1B SET domain-mutant cells. These data indicated that SETD1B was required for H3K4me3 breadth and MYC expression.
