Figure 2. Endogenous Tau Exists in Dendrites.
Tau immunoprecipitates with PSD95, a postsynaptic protein, and regulates the association of PSD-95 with NMDAR subunits and the tyrosine kinase Fyn. Overexpression of a human N-terminal truncation of tau (Δtau74, light grey) or knocking out tau (tau−/−, dark grey) reduced the amount of NR1, NR2a, NR2b, and Fyn within PSD95 complexes.
