A dominant negative Zbtb2 construct stabilizes the interaction with the Ep400 complex.A, Nanog>GFP intensities after switching from 2iLIF to N2B27 +CHIR +bFGF in the presence of DOX of indicated genotypes. B, volcano plot of protein enrichments in AP-MS of mESCs overexpressing ZBTB2-HAF compared with those overexpressing ZBTB2-AVI. ZBTB2 and partner TFs are indicated in blue, NuRD subunits in red, HiRA subunits in green, and Ep400 subunits in orange. AP-MS, affinity purification–MS; bFGF, basic FGF; CHIR, CHIR99021; HiRA, histone regulator A; N2B27, chemically defined medium; NuRD, nucleosome remodeling and deacetylase; TFs, transcription factors.
