Protein interactions are fundamental to the proper functioning of cells, and aberrant formation or regulation of protein interactions is at the heart of many diseases, including cancer. The advancement of methods to study the identity, function, and regulation of protein complexes makes possible the understanding of how those complexes malfunction in human diseases. New methodologies in mass spectrometry, microscopy, and protein structural analysis are rapidly advancing the amount and quality of the data, as well as the level of detail that can be obtained from experiments. With this progress, the questions that can be addressed and the biological landscape are changing. This series of minireviews highlights methodological advances and how they have been applied in novel ways to explore the function and regulation of pathways and dynamic networks in cells.
