The centrosome provides an intracellular anchor for the cytoskeleton, regulating cell division, cell migration, and cilia formation. We used spatial proteomics to elucidate protein interaction networks at the centrosome of human induced pluripotent stem cell-derived neural stem cells (NSCs) and neurons. Centrosome-associated proteins were largely cell type-specific, with protein hubs involved in RNA dynamics. Analysis of neurodevelopmental disease cohorts identified a significant overrepresentation ...

The centrosome acts as the cell’s microtubule organizing center, supporting cell division and the extension of cilia and neurites. Newly born neurons require the microtubule organizing activity of centrosomes to migrate away from their birthplace at the ventricle. O’Neill et al. analyzed the centrosome proteome of human induced pluripotent stem cell–derived neural stem cells and neurons. The neural centrosome proteome contains a variety of RNA-binding/modifying proteins, including an RNA-splicing ...
