Abstract
Protein activities and interactions are determined by their subcellular localization. Elucidating the network of protein-protein interactions at a spatial resolution is essential for understanding the complexity of protein functions, their regulation, and cellular processes. Here, we present a protocol to determine the subcellular localization of protein interactions in non-transformed murine keratinocytes. We describe steps for nucleus/cytoplasm fractionation, immunoprecipitation from these fractions, and immunoblotting. We then detail binding quantification. For complete details on the use and execution of this protocol, please refer to Müller et al. (2023).1.
