CBX7 inhibits USP26. 1 / 1
| 1

"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."
