6 Scientific objectives of the HUPO HLPP
Generation of Compiled Expression Profile of Liver (Proteome): Comprehensive analysis of human liver protein constituents in health and disease states. Establishment of Subcellular Localization Profile: Determination of protein localization and Profile of Sub-cellular proteome. Networking of Liver Proteins Linkage Map (Interactome): Comprehensive analysis of liver protein-protein interactions and networks of liver proteome. Elucidation of Protein Modification Profile: Systematic analysis of post-translational modifications of liver proteome Bridging Liver Proteome Project and Plasma Proteome Project. Parallel coordination of these two initiatives with respect to resources, technology, and knowledge database will be achieved in order to discover biomarkers. Construction of a Knowledge Database: Integration and correlation of human liver proteome with liver transcriptome and human genome

7 New strategy of HPP NATURE，452 (920), 2008 After serveral years’ augument & discussion, people seems come to a consensus. This is the new strategy of HPP. 该思路与我们在HLPP中提出的两谱两图三库的总体思路基本吻合。 The cost “is absolute peanuts when you consider the importance of mapping the building blocks of life”——Mathias Uhlen

8 Proteomics - globally investigate the biological system
Proteome：The whole protein map of an organism, such as cell, tissue, body fluid. Topics: The protein expression, modification, quantification et al. Methods: Experiment observations +background knowledge, collection and integration 蛋白质组学的基本研究策略是：利用质谱、电泳、芯片等实验观测技术观测生物系统，包括蛋白质的表达、定量、修饰等信息，然后与蛋白质知识库、数据库整合分析，推测生物系统的状态，例如疾病状态。 其中质谱技术是其中最重要的观测手段，具有高通量、高灵敏度等特点。 质谱数据的分析就是从质谱数据中解析蛋白质的存在状态，是蛋白质组生物信息学的重要研究内容。 Mass spectrometer is one of the most important instrument in proteomics

9 Technical routes employed for proteome analysis

10 The usage of MS data Biological aspect
Identification of peptides and proteins PTMs: types and sites Quantification of peptides and proteins … Technique aspects The improvement of experimental strategy, instrument design The discovery of the physical and chemical elements of experiments 质谱数据的用途： 1、生物学方面：肽段蛋白质的鉴定；翻译后修饰分析，包括类型和位点分析；定量分析； 2、技术方面：实验策略的改进，仪器平台的改进和设计；分析实验的物理化学原理，建立实验数据产出模型，例如MS/MS图谱预测问题，ESI电离模型，的哦偶可以用于搜库鉴定
