Mmp1 and Mmp2 repress functional differentiation of the NMJ. (A) NMJ electrophysiology two-electrode voltage-clamp (TEVC) records showing motor nerve stimulation evoked excitatory junctional currents (EJCs) from genetic control (w¹¹¹⁸), mmp1^2/Q273*, mmp2^ss218/Df, UH1>Timp and UH1>mmp1+2^RNAi (dblRNAi). (B) Quantified EJC amplitudes for denoted genotypes normalized to genetic controls. See Fig. S2 for mEJC analyses. See Table S2 for raw data values and sample sizes. *P<0.05, **P<0.01, ***P<0.001; NS, not significant.
