丝裂原活化蛋白激酶(MAPK)途径形成哺乳动物细胞内信号转导的主干。在这里,我们应用系统的实验和计算方法来绘制人类mapk相关蛋白与其他细胞机制之间的2,269种相互作用,并将这些数据组装成功能模块。641个相互作用的核心网络得到了多种证据的支持,包括酵母的保存。利用siRNA敲低,我们揭示了大量新的相互作用物可以调节MAPK介导的信号传导。我们发现Na-H交换器NHE1是一组新的MAPK的支架,将HSP90伴侣蛋白连接到MAPK途径,并鉴定MUC12是酵母信号粘蛋白Msb2的人类类似物。这项研究提供了大量的MAPK相互作用资源以及相应的克隆文库。它说明了一种基于实验衍生的蛋白质相互作用图的功能改进的探测信号网络的方法。
Mitogen Activated Protein Kinase (MAPK) pathways form the backbone of signal transduction within the mammalian cell. Here, we apply a systematic experimental and computational approach to map 2,269 interactions between human MAPK-related proteins and other cellular machinery and to assemble these data into functional modules. A core network of 641 interactions is supported by multiple lines of evidence including conservation with yeast. Using siRNA knockdowns, we reveal that a significant number of novel interactors can modulate MAPK mediated signaling. We uncover the Na-H exchanger NHE1 as a scaffold for a novel set of MAPKs, link HSP90 chaperones to MAPK pathways, and identify MUC12 as the human analogue to the yeast signaling mucin Msb2. This study makes available a large resource of MAPK interactions along with the accompanying clone libraries. It illustrates a methodology for probing signaling networks based on functional refinement of experimentally-derived protein interaction maps.
