Summary: Post-translational modifications (PTMs) on histones play essential roles in cell fate decisions during development. However, how these PTMs are recognized and coordinated remains to be fully illuminated. Here, we show that BRPF1, a multi-histone binding module protein, is essential for pluripotency in human embryonic stem cells (ESCs). BRPF1, H3K4me3, and H3K23ac substantially co-occupy the open chromatin and stemness genes in hESCs. BRPF1 deletion impairs H3K23ac in hESCs and leads to closed chromatin accessibility on stemness genes and hESC differentiation as well. Deletion of the N terminal or PHD-zinc knuckle-PHD (PZP) module in BRPF1 completely impairs its functions in hESCs while PWWP module deletion partially impacts the function. In sum, we reveal BRPF1, the multi-histone binding module protein that bridges the crosstalk between different histone modifications in hESCs to maintain pluripotency.
