Project description:To determine how the mutant TBK1-E696K protein impacts autophagosomes, we performed autophagosome content profiling using protease protection coupled APEX2 proximity proteomics of autophagosomes of homozygous TBK1-E696K knockin and wiltype mouse embryonic fibroblasts (MEFs) transfected with a APEX2-LC3 as previously described in Zellner et al. 2021 Molecular Cell.
