    By identifying MYC protein-protein interactors, we aim to gain a deeper mechanistic understanding of MYC as a regulator of gene transcription and potent oncoprotein. This information can then be used to devise strategies for disrupting critical MYC protein-protein interactions to inhibit MYC-driven tumorigenesis. In this chapter, we discuss four techniques to identify and validate MYC-interacting partners. First, we highlight BioID, a powerful discovery method used to identify high-confidence proximal interactors in living cells. We also discuss bioinformatic prioritization strategies for the BioID-derived MYC-proximal complexes. Next, we discuss how protein interactions can be validated using techniques such as in vivo-in vitro pull-down assays and the proximity ligation assay (PLA). We conclude with an overview of biolayer interferometry (BLI), a quantitative method used to characterize direct interactions between two proteins in vitro. Overall, we highlight the principles of each assay and provide methodology necessary to conduct these experiments and adapt them to the study of interactors of additional proteins of interest.
