"For example, Oct4 and Sox2 protein levels are regulated by the E3 ligase WWP2, and ubiquitin-specific-processing protease 21 (Usp21) deubiquitinates and stabilizes Nanog, which maintains pluripotency, while FBXW8, an E3 ligase, ubiquitinates and destabilizes Nanog, thereby promoting ESC differentiation."
