(a) RFP-tagged WT and mutant variants of the Shank3 N-terminus (SPN + Ank domains), or mRFP alone, were coexpressed in 293 T cells with a GFP-tagged C-terminal fragment of α-Fodrin20,23. After cell lysis, RFP-tagged proteins were immunoprecipitated using the mRFP-trap matrix. Input and precipitate samples were analysed by Western blotting using mRFP- (upper panels) and GFP-specific antibodies (lower panels). (b) Quantitative analysis. Signal intensities in IP samples for α-Fodrin were divided by IP signals for mRFP-Shank3 variants. ****Significantly different from WT, p < 0.0001; data from three independent experiments; ANOVA, followed by Dunnett’s multiple comparisons test.
