"ChIP-qPCR of the promoters of Sox2, Nanog, Oct4, and Cbx7 in Usp26 differentiated ESCs on day 6 revealed binding of USP26, CBX4, CBX6, H2A-ubi1, and H3K27me3 to the Sox2, Nanog, and Cbx7 promoters, suggesting that promoter binding of these components led to a decrease in pluripotency gene expression."

"To understand how Usp26 expression is regulated, we assessed the promoter binding activity of Usp26 by PRC1 subunits using the ChIP-qPCR assay during RA induced ESC differentiation, and observed that PRC1 components PCGF2 and Cbx7 occupation as well as H2A-ubi1 modifications decreased significantly in Usp26 promoter, thus indicating that CBX7 containing PRC1 complex is a potential repressor of Usp26."

"In our current study, we screened several AR related USPs, including USP7, USP12, USP14, USP22, and USP26 and found that the USP26 activity was repressed by the induced cellular ROS, which is responsible for AR/ARv7 protein degradation and Enz sensitivity increase by ABT263."
