  1. Proteins like FUS, hnRNPA1, hnRNPA2, and TDP43 are known to form reversible phase separations, as well as irreversible amyloid aggregates. Numerous mutations occurring in the head domain of KRT8 were also identified, primarily associated with liver disease. Mutations in proteins GATAD1 (GATA zinc finger domain-containing 1) and PURA (transcriptional activator of Pur-alpha) were also identified by the in silico screen.
