摘要:

去泛素化酶是蛋白质泛素系统中的重要水解酶,通过逆转泛素化调控蛋白泛素化和去泛素化的动态平衡,在调节蛋白质稳定性、细胞信号转导和细胞凋亡等生物过程中发挥重要作用。卵巢肿瘤结构域蛋白酶(OTU)域泛素醛结合蛋白2(OTUB2)作为去泛素化酶家族成员,通过调节多种底物的泛素化水平,在DNA损伤、信号转导、细胞代谢和肿瘤发生发展中发挥关键作用。OTUB2可在多种癌症中异常表达,且作为调控因子影响癌细胞的生长发育、增殖、迁移及侵袭,与癌症患者的预后有密切关联,可能成为一种新型癌症治疗靶点和预后生物标志物。目前关于OTUB2单一分子机制的研究较多,但针对其在癌症中作用的综述类报道较少。现基于国内外有关OTUB2的研究成果,对OTUB2的生物学功能、相关信号通路及其在癌症研究中的最新进展进行综述,分析OTUB2在癌症患者治疗和预后评估中的应用,为未来针对OTUB2的研究提供新思路。

Abstract:

Deubiquitinating enzymes are important hydrolases in the protein ubiquitin system, which regulate the dynamic balance of protein ubiquitination and deubiquitination by reversing ubiquitination, and play important roles in biological processes such as regulating protein stability, cell signal transduction, and cell apoptosis. As a member of the deubiquitinating enzyme family, ovarian tumor domain-containing protease (OTU) domain ubiquitin aldehyde binding 2 (OTUB2) can play a key role in DNA damage, signal transduction, cell metabolism, and tumorigenesis by regulating the ubiquitination levels of various substrates. OTUB2 can be abnormally expressed in various cancers, and as a regulatory factor, it significantly affects the growth, development, proliferation, migration, and invasion of cancer cells, and is closely related to the prognosis of the patients, potentially becoming a novel cancer therapeutic target and prognostic biomarker. Currently, there are many studies on the molecular mechanisms of OTUB2, but there are few review reports focusing on its role in cancer. Based on the research results about OTUB2 at home and abroad, this article reviewed the biological function of OTUB2, related signaling pathways, and its latest progress in cancer research, analyzed the application of OTUB2 in cancer treatment and prognosis evaluation, and provided new ideas for future research on OTUB2.
