光交联方法可用于绘制活细胞背景下的相互作用组网络。光交联方法依赖于使用代谢工程或遗传密码扩展来将氨基酸或糖的光交联类似物掺入细胞生物分子中。免疫学和质谱技术用于分析交联复合物,从而定义特定的相互作用组。因为光交联可以在天然的细胞环境中进行,所以它可以用于定义上下文依赖的相互作用。光交联方法也非常适合确定相互作用组动力学、绘制相互作用界面以及识别本质上无序的蛋白质和糖蛋白参与的瞬时相互作用。在这里,我们讨论了应用基于细胞的光交联的免疫细胞信号转导,转录,膜蛋白动力学,核质运输和分子伴侣辅助蛋白质折叠的具体问题的研究。
Photocrosslinking approaches can be used to map interactome networks within the context of living cells. Photocrosslinking methods rely on use of metabolic engineering or genetic code expansion to incorporate photocrosslinking analogs of amino acids or sugars into cellular biomolecules. Immunological and mass spectrometry techniques are used to analyze crosslinked complexes, thereby defining specific interactomes. Because photocrosslinking can be conducted in native, cellular settings, it can be used to define context-dependent interactions. Photocrosslinking methods are also ideally suited for determining interactome dynamics, mapping interaction interfaces, and identifying transient interactions in which intrinsically disordered proteins and glycoproteins engage. Here we discuss the application of cell-based photocrosslinking to the study of specific problems in immune cell signaling, transcription, membrane protein dynamics, nucleocytoplasmic transport, and chaperone-assisted protein folding.
