SUMO(小泛素样修饰剂)蛋白的翻译后修饰已被证明可以调节蛋白质的多种功能,包括蛋白质稳定性、染色质组织、转录、DNA 修复、亚细胞定位、蛋白质-蛋白质相互作用和蛋白质稳态。 SENP(sentrin/SUMO 特异性蛋白酶)调节 SUMO 的前体加工和解偶联以控制细胞机制。 SENP3 是 SENP 家族成员之一,可解偶联靶蛋白以改变蛋白质修饰。 SUMO和SENP3的修饰作用对于维持SUMO化的平衡、保证正常的蛋白质功能和细胞活性至关重要。 SENP3 在生理条件下充当氧化应激反应分子。病理条件下,如果蛋白质的SUMO化过程受到SENP3水平变化的影响,就会引起细胞反应,最终导致细胞活动异常以及人类疾病的发生和发展,包括心血管疾病、神经系统疾病以及各种癌症等。在这篇综述中,我们总结了 SENP3 在正常生理和病理条件下的关键作用以及在各种疾病中的潜在临床意义的最新进展。单独靶向 SENP3 或与现有疗法相结合可能为这些疾病的治疗提供强大的靶向治疗策略。
Post-translational modification by SUMO (small ubiquitin-like modifier) proteins has been shown to regulate a variety of functions of proteins, including protein stability, chromatin organization, transcription, DNA repair, subcellular localization, protein–protein interactions, and protein homeostasis. SENP (sentrin/SUMO-specific protease) regulates precursor processing and deconjugation of SUMO to control cellular mechanisms. SENP3, which is one of the SENP family members, deconjugates target proteins to alter protein modification. The effect of modification via SUMO and SENP3 is crucial to maintain the balance of SUMOylation and guarantee normal protein function and cellular activities. SENP3 acts as an oxidative stress-responsive molecule under physiological conditions. Under pathological conditions, if the SUMOylation process of proteins is affected by variations in SENP3 levels, it will cause a cellular reaction and ultimately lead to abnormal cellular activities and the occurrence and development of human diseases, including cardiovascular diseases, neurological diseases, and various cancers. In this review, we summarized the most recent advances concerning the critical roles of SENP3 in normal physiological and pathological conditions as well as the potential clinical implications in various diseases. Targeting SENP3 alone or in combination with current therapies might provide powerful targeted therapeutic strategies for the treatment of these diseases.
