Title	Proteomic profiling of centrosomes across multiple cell and tissue types by a new affinity capture method
Description	Centrosomes are small cytoplasmic organelles that play fundamental roles in a range of cellular processes. Nearly all vertebrate cell types contain centrosomes, but whether centrosome composition and function differ between cell types, tissues and pathologies remains an outstanding question. Until now, probing centrosome composition has relied on proteomic profiling of centrosomes obtained by consecutive sucrose density gradient centrifugations, requiring up to one billion cells, thus rendering studies with multiple conditions cumbersome. Here we describe centrosome affinity capture (CAPture)-mass spectrometry (MS), a method that achieves high-coverage proteomes from 20-30 million cells. Utilising a biotin-labelled peptide derived from the CCDC61 protein, CAPture isolates intact centrosomes in a manner dependent on Ninein, a conserved centrosome component. CAPture-MS performs well across several untransformed and primary cell lines, thereby enabling comparisons of high-resolution centrosome proteomes. Using distal appendage proteins as an example, we demonstrate the utility of CAPture-MS for dissecting hierarchical interactions within the centrosome. Overall CAPture-MS represents a powerful tool to unveil temporal, regulatory, cell type- and tissue-specific changes in centrosome proteomes in health and disease.
