The FBXL10/KDM2B scaffolding protein associates with novel polycomb repressive complex-1 to regulate adipogenesis

Abstract

Background: Polycomb repressive complex PRC1 is an epigenetic regulator of cellular differentiation. However, its function during adipogenesis is unknown. Results: FBXL10/KDM2B recruited noncanonical PRC1 complex in F-box and LRR motifs dependent on cell cycle-related genes and Pparg genes and repressed 3T3-L1 adipogenesis. Conclusion: Noncanonical PRC1 complex containing FBXL10/KDM2B regulates adipogenesis. Significance: Our findings revealed a novel epigenetic mechanism of adipogenesis.
