阐明内源性细胞蛋白-蛋白相互作用及其网络是生物学研究中最需要的。在这里,我们报告了我们的内源性人类共调节蛋白复合物网络的研究,该网络通过基于综合质谱的分析获得了3290种亲和纯化。通过在复杂分离过程中保留弱蛋白质相互作用,并利用大型数据集中的高水平互惠,我们确定了许多未报道的蛋白质关联,例如由ZMYND8、ZNF687和ZNF592形成的转录网络。此外,我们的工作揭示了共享共同蛋白质的网络内部的分层相互作用,提供了由最小内源性模块(memo),功能性unicore和调节复合物-复合物相互作用网络(CCIs)组成的细胞蛋白质组的概念组织。该资源将有效地填补空白,将相关基因组研究与蛋白质组中转录调节蛋白功能的理解联系起来,以制定和测试新的假设。
Elucidation of endogenous cellular protein-protein interactions and their networks is most desirable for biological studies. Here we report our study of endogenous human coregulator protein complex networks obtained from integrative mass spectrometry-based analysis of 3,290 affinity purifications. By preserving weak protein interactions during complex isolation and utilizing high levels of reciprocity in the large dataset we identified many unreported protein associations, such as a transcriptional network formed by ZMYND8, ZNF687 and ZNF592. Furthermore, our work revealed a tiered interplay within networks that share common proteins, providing a conceptual organization of a cellular proteome composed of minimal endogenous modules (MEMOs), functional uniCOREs and regulatory complex-complex interaction networks (CCIs). This resource will effectively fill a void in linking correlative genomic studies with an understanding of transcriptional regulatory protein functions within the proteome for formulation and testing of new hypotheses.
