Ubiquitination is a reversible cellular process mediated by ubiquitin-conjugating enzymes, whereas deubiquitinating enzymes (DUBs) detach the covalently conjugated ubiquitin from target substrates to counter ubiquitination. DUBs play a crucial role in regulating various signal transduction pathways and biological processes including apoptosis, cell proliferation, DNA damage repair, metastasis, differentiation, etc. Since the transforming growth factor-β (TGF-β) signaling pathway participates in various cellular functions such as inflammation, metastasis and embryogenesis, aberrant regulation of TGF-β signaling induces abnormal cellular functions resulting in numerous diseases. This review focuses on DUBs regulating the TGF-β signaling pathway. We discuss the molecular mechanisms of DUBs involved in TGF-β signaling pathway, and biological and therapeutic implications for various diseases.
泛素化是一种由泛素连接酶介导的可逆细胞过程,而去泛素化酶(DUBs)则将共价连接的泛素从靶底物上脱离,以抵消泛素化。DUBs 在调节各种信号转导途径和生物过程中发挥着关键作用,包括细胞凋亡、细胞增殖、DNA 损伤修复、转移、分化等。由于转化生长因子-β(TGF-β)信号通路参与炎症、转移和胚胎发生等多种细胞功能,TGF-β信号通路的异常调节导致异常的细胞功能,从而导致许多疾病。本综述重点介绍了 DUBs 对 TGF-β信号通路的调节。我们讨论了参与 TGF-β信号通路的 DUBs 的分子机制,以及它们在各种疾病中的生物学和治疗意义。
