Fig. 4 — USP26 interacts with PRC1 components. a 293T cells were transfected with HA-tagged RING1A, RING1B, RYBP, PCGF1, PCGF2, BMI1, CBX4, CBX6, CBX7, or CBX2 plus FLAG-hUSP26 or empty vector. Following IP with anti-FLAG beads, specific proteins were analyzed by western blotting using anti-HA antibody. b Mouse ESCs were infected with or without mouse USP26 lentivirus, and cell extracts were harvested at different time points, immunoprecipitated with anti-USP26 antibody, and analyzed by western blotting using specific antibodies, as indicated. c RING1A, CBX4, and CBX6 knockout (KO) 293T cells were transfected with FLAG-USP26, cell extracts were harvested, immunoprecipitated with anti-FLAG antibody, and analyzed by western blotting using specific antibodies, as indicated
