泛素化(Ubiquitylation)是一种常见的蛋白质修饰,调节细胞内的许多过程。这种修饰通常通过泛素与靶蛋白上的赖氨酸残基的共价结合来实现,并且通过三种酶的存在来催化:活化酶(E1)、泛素缀合酶(E2)和泛素蛋白连接酶(E3)。近年来,在哺乳动物系统中,泛素化已上升为免疫和微生物致病的主要信号调节剂。然而,关于泛素如何与载体免疫学特异性相关的知之甚少。在这里,我们提供了一个简短的概述泛素生物化学和描述如何泛素化调节免疫反应的节肢动物的医学相关性。我们还讨论了文献中的科学空白,并建议,与哺乳动物相似,泛素是医学上重要的节肢动物免疫的主要调节因子。
Ubiquitination (Ubiquitylation) is a common protein modification that regulates a multitude of processes within the cell. This modification is typically accomplished through the covalent binding of ubiquitin to a lysine residue onto a target protein and is catalyzed by the presence of three enzymes: an activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and ubiquitin-protein ligase (E3). In recent years, ubiquitination has risen as a major signaling regulator of immunity and microbial pathogenesis in the mammalian system. Still, little is known about how ubiquitin relates specifically to vector immunology. Here, we provide a brief overview of ubiquitin biochemistry and describe how ubiquitination regulates immune responses in arthropods of medical relevance. We also discuss scientific gaps in the literature and suggest that, similar to mammals, ubiquitin is a major regulator of immunity in medically-important arthropods.
