The present invention provides methods for analyzing proteomes, as cells or lysates. The analysis is based on the use of probes that have specificity to the active form of proteins, particularly enzymes and receptors. The probes can be identified in different ways. In accordance with the present invention, a method is provided for generating and screening compound libraries that are used for the identification of lead molecules, and for the parallel identification of their biological targets. By appending specific functionalities and/or groups to one or more binding moieties, the reactive functionalities gain binding affinity and specificity for particular proteins and classes of proteins. Such libraries of candidate compounds, referred to herein as activity-based probes, or ABPs, are used to screen for one or more desired biological activities or target proteins.
本发明提供了用于分析蛋白质组的方法,例如细胞或裂解物。该分析基于具有特异性对蛋白质的活性形式的探针的使用,特别是酶和受体。这些探针可以通过不同的方式进行识别。根据本发明,提供了一种用于生成和筛选化合物库的方法,用于识别引物分子,并并行识别它们的生物学靶标。通过向一个或多个结合基团添加特定的功能性和/或基团,反应性功能性获得了对特定蛋白质和蛋白质类的结合亲和性和特异性。这种候选化合物库,本文称为活性探针(ABPs),用于筛选一个或多个所需的生物活性或靶标蛋白质。
