An Mll4/COMPASS-Lsd1 epigenetic axis governs enhancer function and pluripotency transition in embryonic stem cells.

ABSTRACT: Chromatin regulators control cellular differentiation by orchestrating dynamic developmental gene expression programs, and hence, malfunctions in the regulation of chromatin state contribute to both developmental disorders and disease state. Mll4 (Kmt2d), a member of the COMPASS (COMplex of Proteins ASsociated with Set1) protein family that implements histone H3 lysine 4 monomethylation (H3K4me1) at enhancers, is essential for embryonic development and functions as a pancancer tumor suppressor. We define the roles of Mll4/COMPASS and its catalytic activity in the maintenance and exit of ground-state pluripotency in murine embryonic stem cells (ESCs). Mll4 is required for ESC to exit the naive pluripotent state; however, its intrinsic catalytic activity is dispensable for this process. The
