UTX is a histone H3 lysine 27 demethylase required for development. However, the mechanisms underlying developmental gene regulation by UTX are unclear. Here, we discovered a molecular interaction between UTX and 53BP1 that regulates gene expression in a human neurogenesis model. Human 53BP1 contains a UTX-binding site that diverges from its mouse homolog by 41%, and our data suggest that the UTX-53BP1 interaction is conserved in primates but not rodents. ChIP-Seq revealed that the genome-wide targets of UTX and 53BP1 overlap by 84%. We used CRISPR-Cas9 to generate mutations of 53BP1 and UTX in human embryonic stem cells, and found that both 53BP1 and UTX are required to promote the expression of hundreds of neurogenic genes during neural differentiation. Further, 53BP1 is required for human neural progenitor differentiation into neurons. Our findings suggest that the UTX-53BP1 interaction controls gene expression important for neural differentiation in humans.
