摘要:


文题释义:
棕榈酰基转移酶:是一类保守的含Asp-His-His-Cys(DHHC)结构域的酶,在不同细胞器中具有特定的定位,共同负责催化蛋白质的S-棕榈酰化修饰。棕榈酰基转移酶通过将棕榈酸(16碳脂肪酸)共价连接到目标蛋白质的半胱氨酸残基上,参与调控蛋白质的相互作用及稳定性,对组织稳态具有重要意义。
锌指DHHC型棕榈酰转移酶5:是棕榈酰基转移酶家族的重要成员,主要定位于质膜。它通过催化蛋白质的棕榈酰化修饰,参与胞质分裂、突触可塑性等多种生理过程,其异常表达已被证明与呼吸系统疾病、炎症、癌症等多种疾病的发生和发展密切相关,可作为多种疾病治疗的潜在靶点。

背景:蛋白质S-棕榈酰化是一种可逆的翻译后修饰,直接影响蛋白质的稳定性、亚细胞定位及与其他分子的相互作用。在哺乳动物细胞中,棕榈酰化由23-24种含有Asp-His-His-Cys(DHHC)共同基序的棕榈酰基转移酶催化。近年来,S-棕榈酰化在疾病中的重要作用引起了广泛关注,越来越多的研究试图通过靶向棕榈酰化及其催化酶,探索治疗疾病的新策略。其中,锌指DHHC型棕榈酰转移酶5(Palmitoyl transferase 5,ZDHHC5)是棕榈酰基转移酶家族中较为特殊的成员,它主要定位于质膜,通过催化棕榈酸酯添加到多种蛋白质底物上,参与多种生物过程。
目的:简要介绍棕榈酰化的生物化学过程及其检测方法,阐明ZDHHC5在胞质分裂、突触形成与可塑性、细胞程序性死亡等生理过程中的作用,并总结近年来ZDHHC5在呼吸系统疾病、癌症等病理方面的研究进展。
方法:由第一作者以“ZDHHC5、DHHC5或Palmitoyl transferase 5”为英文检索词,以“棕榈酰基转移酶5”为中文检索词,运用计算机在PubMed和CNKI数据库检索近年来有关于ZDHHC5研究的相关文献,检索时限设置为2011年1月至2025年3月,筛选后进行系统分析,对ZDHHC5在组织稳态和疾病中的作用机制进行归纳与总结。
结果与结论:ZDHHC5作为一种关键的动态棕榈酰化修饰酶,通过直接修饰PCDH7、TrpM7、δ-catenin、NCX1、NOD2、MLKL等关键底物,或与GOLGA7等蛋白形成复合物,调控细胞分裂与分化、离子通量调节、突触形成与可塑性、细胞自噬与程序性死亡、细胞内膜运输、细胞黏附、少突胶质细胞及髓腔鞘形成,以及免疫信号调节等多种重要生理过程。在病理状态下,ZDHHC5的异常表达可能通过影响EZH2、SSTR5、INCENP等蛋白的棕榈酰化水平,促进神经胶质瘤、呼吸道疾病、心脏疾病、炎症、脂肪肝、糖尿病视网膜病变、精神分裂症等多种疾病的发生发展,表明其功能异常可能在多种疾病的发生机制中起到重要作用。未来研究应重点关注ZDHHC5的底物特异性识别机制,以及在不同生理和病理条件下的功能调控作用。同时,开发针对ZDHHC5的小分子抑制剂,并与跨学科技术整合应用,为基于棕榈酰化修饰的精准治疗策略提供新的方向,最终推动相关疾病的诊断和治疗。

Abstract: BACKGROUND: Protein S-palmitoylation is a reversible post-translational lipid modification that directly influences protein stability, subcellular localization and interactions with other molecules. It is catalyzed in mammalian cells by 23-24 palmitoyl acyltransferases (PATs) that share the common Asp-His-His-Cys (DHHC) motif. Recent studies have highlighted the important role of S-palmitoylation in disease, and increasing studies have attempted to explore new therapeutic potentials in diverse diseases, driving efforts to target palmitoylation and its catalytic enzymes. Among these, palmitoyl transferase 5 (ZDHHC5) is a more specific member of the palmitoyl group transferase family, which is a plasma membrane-localized PAT that palmitoylates a wide variety of substrates, thereby influencing multiple biological processes.
OBJECTIVE: To provide an overview of the biochemical process of palmitoylation and its detection methods, to elucidate the role of ZDHHC5 in physiological processes such as cytoplasmic division, synapse formation and plasticity, and programmed cell death, and to summarize recent research progress on ZDHHC5 in cancer, respiratory diseases and other pathologies.
METHODS: The first author conducted a systematic literature search in PubMed and CNKI databases for relevant literature on ZDHHC5 research in recent years, using “ZDHHC5, DHHC5 or palmitoyl transferase 5” as the search terms in English and “palmitoyl transferase 5” as the search term in Chinese. The search period was set from January 2011 to March 2025. After screening the retrieved literature for relevance and quality, the remaining literature was used to analyze the role and mechanism of ZDHHC5 in tissue homeostasis and diseases. 
RESULTS AND CONCLUSION: ZDHHC5, a key palmitoyl transferase that dynamically modifies protein palmitoylation, regulates cell division and differentiation, ion flux regulation, synapse formation and plasticity, autophagy and programmed cell death, intracellular membrane transport, cell adhesion, oligodendrocyte and myelin sheath formation, and immune signaling regulation, either by direct modification of key substrates, such as PCDH7, TrpM7, δ-catenin, NCX1, NOD2, and MLKL, or by formation of a complex with proteins, such as GOLGA7. Under pathological conditions, the aberrant expression of ZDHHC5 may promote the development of glioma, pancreatic cancer, lung cancer and other cancers by affecting the palmitoylation levels of EZH2, SSTR5, and INCENP and other proteins. In addition, ZDHHC5 promotes the occurrence and development of various diseases such as respiratory disease, schizophrenia, heart disease, inflammation, fatty liver, diabetic retinopathy, suggesting that its aberrant function may play an important role in the pathogenesis of multiple diseases. Future studies should focus on the substrate-specific recognition mechanism of ZDHHC5 and the regulation of its function under different physiological and pathological conditions. Meanwhile, the development of small molecule inhibitors targeting ZDHHC5 and the integrated application of interdisciplinary technologies will provide a new direction for precision therapeutic strategies based on palmitoylated modifications, which will ultimately promote the diagnosis and treatment of related diseases.
