Cys32-dependent CAP2 dimer is relevant for synaptic transmission potentiation upon LTP induction. (A) Electrophysiological recordings of mEPSCs before and after chemical LTP (cLTP) induction in 15 DIV hippocampal neurons. Representative mEPSC traces. (B) Differently from CTRL and shr-wt-CAP2 cells, CAP2-shRNA and CAP2-shRNA+shr-C32G-CAP2 neurons are unable to undergo cLTP. mEPSCs amplitude (normalized values): CTRL = 1 ± 0.03 (n =18) versus cLTP: 1.26 ± 0.07 (n = 22); CAP2-shRNA: 1 ± 0.02 (n =15) versus cLTP: 1 ± 0.02 (n =20); shRNA+shr-wt-CAP2: 1 ± 0.04 (n =19) versus cLTP: 1.25 ± 0.05 (n =23); shRNA+shr-C32G-CAP2: 1 ± 0.031 (n =18) versus cLTP: 1 ± 0.04 (n =26). One-way ANOVA, Holm-Sidak's multiple comparisons test: P <0.0001.
