Together, IPA analysis of enriched “Molecular and Cellular Functions” along with “Canonical Pathways” and interaction networks of Tau revealed clusters of proteins that were associated with cellular organization systems, protein clearance, stress response pathways, metabolic processes, and neurotransmission providing further insight into the individual proteins and protein complexes in proximity to pathological forms of Tau from the post‐mortem tissue of PSP patients. Here, MAPT is linked to supranuclear palsy, progressive, 1.
