Proximity-labeling using engineered biotin ligases TurboID and miniTurbo enables detection of cell-type-specific and low abundance protein complexes and subcellular proteomes in Arabidopsis and other plants.
Although cellular organelles show a functional deterioration in aging, genetic loci associated with common age-associated disease instead nominate nuclear transcription factors across several age-related diseases.
A combination of spatial proteomic and autophagic flux approaches was used to reveal the landscape of turnover of damaged lysosomes, demonstrating a key role for the autophagy receptor TAX1BP1 and its associated kinase TBK1 in both HeLa cells and iNeurons.
One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.
Two novel subsets of microglia identified by their unique autofluorescence profiles differ in their subcellular organization, proteomic signatures and in their response to aging and lysosomal dysfunction.
