Protein kinases are key components of most mammalian signal transduction networks and are therapeutically relevant drug targets. Efforts to study protein kinase function would benefit from new technologies that are able to profile kinases in complex proteomes. Here, we describe active site-directed probes for profiling kinases in whole cell extracts and live cells. These probes contain general ligands
蛋白激酶是大多数哺乳动物信号转导网络的关键组成部分,是治疗相关的药物靶点。研究蛋白激酶功能的努力将受益于能够分析复杂蛋白质组中激酶的新技术。在这里,我们描述了用于分析全细胞提取物和活细胞中激酶的活性定点探针。这些探针包含稳定蛋白激酶 ATP 结合位点的特定非活性构象的通用配体,以及允许共价修饰和富集激酶的三氟甲基苯基二氮丙啶和炔部分,分别。一组不同的丝氨酸/苏氨酸和酪氨酸激酶被鉴定为全细胞提取物中这些探针的特定靶标。此外,在活细胞中选择性标记了许多激酶靶标。
