磷酸化蛋白质组学是以高通量对最常见的蛋白质修饰之一进行系统研究,旨在提供健康和疾病中生物系统的控制,反应和通信的详细信息。分析技术和策略的进步,特别是高分辨率质谱仪的贡献,磷酸肽的有效富集,以及快速数据采集和注释,在过去十年中催化了多个系统中信号景观的急剧扩展。虽然磷酸化蛋白质组学是一个必不可少的调查映射高分辨率的信号网络,并找到明显无处不在和广泛的蛋白质组的修改中的相关事件,它提出了巨大的挑战,分离科学,将其从发现到临床实践。在这篇小型综述中,我们总结了目前用于磷酸化蛋白质组学分析的分析工具(重点是MS),在破译临床相关激酶底物网络方面取得的进展,MS用于生物标志物发现和验证,以及磷酸化蛋白质组学用于疾病诊断和个性化医疗的潜力。
Phosphoproteomics is the systematic study of one of the most common protein modifications in high throughput with the aim of providing detailed information of the control, response, and communication of biological systems in health and disease. Advances in analytical technologies and strategies, in particular the contributions of high-resolution mass spectrometers, efficient enrichments of phosphopeptides, and fast data acquisition and annotation, have catalyzed dramatic expansion of signaling landscapes in multiple systems during the past decade. While phosphoproteomics is an essential inquiry to map high-resolution signaling networks and to find relevant events among the apparently ubiquitous and widespread modifications of proteome, it presents tremendous challenges in separation sciences to translate it from discovery to clinical practice. In this mini-review, we summarize the analytical tools currently utilized for phosphoproteomic analysis (with focus on MS), progresses made on deciphering clinically relevant kinase-substrate networks, MS uses for biomarker discovery and validation, and the potential of phosphoproteomics for disease diagnostics and personalized medicine.
