Abstract

Mitochondrial protein homeostasis (proteostasis) keeps the mitochondrial proteome functional. Thus, proteostasis is essential for mitochondrial activity and overall cellular functions, and a reduction in its function corresponds with diseases and aging in humans. Recent studies in various model organisms highlight components and mechanisms of mitochondrial proteostasis from biogenesis, through assembly, to turnover. Key findings include the identification of new components and mechanistic insights into protein import and mitochondrial translation processes, the interconnectivity of protein biogenesis and quality control, and proteolytic degradation machineries. In this review we discuss these advances that improve our current understanding of the inner workings and significance of the mitochondrial proteostasis network in maintaining functional mitochondria.

线粒体蛋白生物发生与质量控制的互联性。
线粒体蛋白质稳态(proteostasis)维持线粒体蛋白质组的功能。因此,蛋白质平衡对线粒体活动和整体细胞功能至关重要,其功能的降低与人类的疾病和衰老相对应。最近对各种模式生物的研究强调了线粒体蛋白酶的组成和机制,从生物发生,到组装,再到周转。主要发现包括鉴定新的成分和蛋白质进口和线粒体翻译过程的机制见解,蛋白质生物发生和质量控制的相互联系,以及蛋白质水解降解机制。在这篇综述中,我们讨论了这些进展,提高了我们目前对线粒体蛋白质平衡网络在维持线粒体功能中的内部工作和意义的理解。

期刊介绍: For over 40 years, Trends in Biochemical Sciences (TIBS) has been a leading publication keeping readers informed about recent advances in all areas of biochemistry and molecular biology. Through monthly, peer-reviewed issues, TIBS covers a wide range of topics, from traditional subjects like protein structure and function to emerging areas in signaling and metabolism. Articles are curated by the Editor and authored by top researchers in their fields, with a focus on moving beyond simple literature summaries to providing novel insights and perspectives. Each issue primarily features concise and timely Reviews and Opinions, supplemented by shorter articles including Spotlights, Forums, and Technology of the Month, as well as impactful pieces like Science & Society and Scientific Life articles.
