Article Title: DAXX promotes SUMOylation of chromatin-trapped DNMT1
doi: 10.1093/jb/mvag011
Figure Lengend Snippet: Non-covalent DNMT1 inhibitor GSK-3484862 induces DAXX-regulated DNMT1 SUMOylation. (A) Xenopus sperm nuclei were incubated in egg extracts supplemented with DMSO, GSK-3484862 or GSK-3484862 and ML-792. Isolated chromatin was analyzed by immunoblotting with indicated antibodies. (B) Immunoblotting results using indicated antibodies following DNMT1 immunoprecipitation of chromatin treated with or without GSK-3484862 for 60 min. The input results are shown in the lower panels. (C) Immunoblotting results of mock-depleted or DAXX-depleted egg extracts using indicated antibodies. (D) Xenopus sperm nuclei were incubated in mock-depleted or DAXX-depleted extracts treated with GSK-3484862 for 60 or 90 min. Isolated chromatin was analyzed by immunoblotting with indicated antibodies.
Article Snippet: For DNMT1 inhibition, egg extracts were incubated with 50 μM 5-aza-dCTP (Jena Bioscience) or with 100 μM GSK-3484862 (MedChemExpress).
