By regulating the ubiquitination and deubiquitination of key proteins, ubiquitin-proteasome system mediates a variety of cellular activities. Ubiquitin C-terminal hydrolase (UCH) is a deubiquitinating enzyme which can remove ubiquitin chains at the end of ubiquited proteins. The abnormal expression of UCH has been found in a variety of tumor tissues, indicating that it participates in the process of tumor development. Here we review the characteristics of UCH members and current understanding about the role of UCH in tumor development, and the potential target for cancer treatment.
泛素—蛋白酶体系统通过调控关键蛋白的泛素化和去泛素化介导多种细胞活动。泛素羧基末端水解酶在多种肿瘤组织中表达异常，作为去泛素化酶家族成员，可移除泛素化蛋白上的泛素分子，从而介导肿瘤发生中关键蛋白的泛素化水平，参与多种肿瘤的发生发展过程。本文对泛素羧基末端水解酶家族成员特点及其在肿瘤发生发展中的作用进行综述，以期为寻找肿瘤治疗新靶点提供线索。
