Abstract: Protein S-palmitoylation, the most common lipid modification with the 16-carbon fatty acid palmitate, provided an important mechanism for regulating protein trafficking and function. This article summarized a family of conserved DHHC proteins with palmitoyltransferase activity that had been discovered from plants to mammals. The method of protein palmitoylation was so concluded. The paper also introduced the research methods of protein palmitoylation, the prediction methods of palmitoylation sites (CSS-Palm, NBA-Palm, TermiNator2), radioactive labeling (radiolabeling with 3H palmitate or 125I-IC16 palmitate) and non-radioactive labeling (chemical labeling and mass spectrometry) to detect palmitoylated proteins. Next, techniques to inhibit protein palmitoylation were described. These included site specific mutagenesis, and treatment of cells with inhibitors of protein palmitoylation, including 2-bromopalmitate, cerulenin, and tunicamycin. Based on the authors’ research directions, the response of protein palmitoylation in plant stress and the application prospect of plant stress resistance were summarized and prospected.

摘要: 蛋白质S-棕榈酰化是最常见的具有16碳脂肪酸棕榈酸酯的脂质修饰形式,调节蛋白质的运输和功能。文中主要概括从植物到哺乳动物中发现的具有棕榈酰基转移酶活性的保守DHHC蛋白家族,并介绍蛋白质棕榈酰化的研究方法,及检测棕榈酰化蛋白质的位点预测方法(CSS-Palm、NBA-Palm、TermiNator2)、放射性标记法(用3H棕榈酸酯或125I-IC16棕榈酸酯)和非放射性标记法(化学标记和质谱法),总结蛋白棕榈酰化的抑制技术以及抑制剂类型(包括2-溴棕榈酸酯、浅蓝菌素和衣霉素)。同时概括蛋白棕榈酰化在植物胁迫中的响应,展望其在植物抗逆中的应用前景。
