DDA analysis has been used for a variety of studies, including the characterization of epidermal growth factor receptor (EGFR) signaling networks12,13, the characterization of the proteome on different mouse organs14,15, identification of protein interaction partners16–18, and description of the role of viral infections in modulating host proteomes18–21, which had been thoroughly covered in a special issue of the journalProteomics22. Here, EGFR is linked to viral infectious disease.
