Palmitoylation is the reversible post-translational addition of a lipid moiety to cysteine residues on targeted proteins. The recent use of proteomic-scale techniques to study protein palmitoylation in multiple organisms has radically changed our understanding of the diversity of proteins and signaling pathways that are affected by palmitoylation. These experiments have made clear that, similarly to phosphorylation, palmitoylation is a regulatory tool that has an impact upon a wide range of essential eukaryotic processes. A recent proteome-level analysis of protein palmitoylation in Plasmodium has revealed the importance of palmitoylation in parasite biology and has raised new and exciting questions about several Plasmodium-specific and virulence-associated processes.
棕榈酰化是一种可逆的翻译后修饰过程,即在靶蛋白的半胱氨酸残基上添加脂质基团。最近,利用蛋白质组学规模的技术研究多种生物体中的蛋白质棕榈酰化,极大地改变了我们对受棕榈酰化影响的蛋白质和信号通路多样性的理解。这些实验清楚地表明,与磷酸化类似,棕榈酰化是一种调节工具,对广泛的真核生物过程都有影响。最近对疟原虫蛋白质棕榈酰化的蛋白质组水平分析揭示了棕榈酰化在寄生虫生物学中的重要性,并对几种疟原虫特有的和与毒力相关的过程提出了新的令人兴奋的问题。
