shRNA against μ2 and HA-μ2 plasmids resistant to shRNA μ2 were constructed as previously described24 (link). 60-mers oligonucleotides containing rat μ2 subunit cDNA target sequences (GTGGATGCCTTTCGCGTCA) of AP-2 were synthesized, annealed, and ligated into pSUPER vector according to manufacturer’s instruction. HA-μ2 construct was generated using Quick Change Site-Directed mutagenesis (Stratagene). The target sequence for shRNA μ2 was mutated to GTGGACGCTTTCCGGGTCA without the amino acid sequence change. EGFP-C2 is from clontech, GFP-Tau, VMAP2-GFP, GFP-synapsin-1, Nav1.6-GFP was cloned as previously described52 (link). GCaMP6f from Addgene30 (link) is conjugated to synaptophysin.
