Abstract
Here we show that Gas7 inhibits phosphorylated tau fibrillogenesis by binding to phosphorylated tau at its non-WW domain, presumably F-BAR domain. We revealed that Gas7 binds to the third repeat domain of tau, the core element of tau oligomerization and the C-terminal domain of tau and alters the conformation not to form fibrils. These results suggest that Gas7 may serve to protect against Alzheimer's disease and other tauopathies by preventing tau fibrillogenesis.
