摘要：

泛素化是真核细胞中最重要的蛋白质翻译后修饰形式之一，可参与调节细胞的各种生理过程，包括细胞周期进程、细胞分化、细胞凋亡以及先天性和适应性免疫反应。目前越来越多的靶向泛素-蛋白酶体系统(UPS)的药物被开发出来。有证据表明，肺动脉高压(PH)发病过程中存在UPS功能紊乱，但其机制尚不明确，也无相关药物应用于临床。本文回顾了UPS的结构和功能，并对PH中功能异常的UPS相关蛋白及其作用机制进行综述，以为临床精准诊断及靶向治疗方案的制定提供新思路。

Abstract：

【Abstract】 Ubiquitination, one of the most important types of post-translational protein modifications in eukaryotic cells, has played a role in regulating various physiological processes including cell cycle progression, cell differentiation, cell apoptosis, and innate and adaptive immune responses. At present, more and more drugs targeting ubiquitin proteasome system (UPS) have been developed. There is evidence that UPS dysfunction exists in the pathogenesis of pathogenesis of pulmonary hypertension (PH) , but its mechanisms was still unclear, and no related-drugs were applied in clinic. This paper reviews the the structure and function of UPS, and summarizes the functional abnormalities of UPS related protein in PH and their mechanism of action, so as to provide new ideas for accurate clinical diagnosis and the formulation of targeted therapy.
