摘要: 高度精准调控的蛋白质合成是维持生命体稳态和功能的重要保障,丙氨酰tRNA合成酶(alanyl-tRNA synthase, AARS1/2)在这一过程中发挥着至关重要的作用。AARS1/2是一类在细胞中合成丙氨酰tRNA的酶,参与基因编码蛋白质的合成,同时也催化蛋白质的赖氨酸丙酰化,从而调节蛋白质功能。本文综述了AARS1/2在蛋白质错误翻译引发疾病进程及其在代谢-免疫交互网络调控中的研究进展,以期更好地理解AARS1/2的病理生理学机制,并为开发潜在治疗药物提供参考。

Abstract: Highly precise regulation of protein synthesis is critical for the homeostasis and functionality of living organisms. Ala-nyl-tRNA synthase (AARS1/2) plays a crucial role in this process. AARS1/2 are a class of enzymes that synthesize ala-nyl-tRNA in cells, participating in protein synthesis encoded by genes, and catalyzing the propionylation of lysine residues in proteins, thereby regulating protein function. This article reviews the research progress on the involvement of AARS1/2 in disease progression induced by protein mistranslation and in the regulation of the metabolic–immune interaction net-work, aiming to better understand the pathophysiological mechanisms of AARS1/2 and to provide a reference for the de-velopment of potential therapeutic drugs.
