STRING was used to determine statistical enrichment of pathways in gene sets generated from the screens31. Two separate gene sets for this analysis were compiled from gene knockouts that downregulated tau and gene knockouts, that upregulated tau from at least two of the mini pool custom array validation screens with an RSA score cut-off of ≤−5. STRING network edge parameters were set at high confidence (0.700) and are represented by the line thickness between nodes. The gene sets were analyzed using multiple sources including Reactome, KEGG, Gene Ontology, and published literature. Networks were determined based on low false discovery rate (<1.2%) and confidence between nodes ranging from high to highest (0.700-0.900) (Supplementary Data 4 and 5).
