Here, we provide a detailed protocol for the analysis of liver macrophage subsets in mice with non-alcoholic fatty liver disease (NAFLD) and early NASH using flow cytometry and immunofluorescence (IF). These methods can be used to assess the composition and localization of macrophage subsets during NASH. For complete details on the use and execution of this protocol, please refer to Daemen et al. (2021).The ascorbate peroxidase APEX2 is commonly used to study the neighborhood of a protein of interest by proximity-dependent biotinylation. Here, we describe a protocol for sample processing compatible with immunoblotting and mass spectrometry, suitable to specifically map the content of autophagosomes and potentially other short-lived endomembrane transport vesicles without the need of subcellular fractionation. By combining live-cell biotinylation with proteinase K digestion of cell homogenates, proteins enriched in membrane-protected compartments can be readily enriched and identified. For complete details on the use and execution of this protocol, please refer to Zellner et al. (2021).Computational generation of new proteins with a predetermined three-dimensional shape and computational optimization of existing proteins while maintaining their shape are challenging problems in structural biology. Here, we present a protocol that uses ProteinSolver, a pre-trained graph convolutional neural network, to quickly generate thousands of sequences matching a specific protein topology. We describe computational approaches that can be used to evaluate the generated sequences, and we show how select sequences can be validated experimentally. For complete details on the use and execution of this protocol, please refer to Strokach et al. (2020).Sequential chromatin immunoprecipitation (C
