Dynamin-1 co-associates with native mouse brain BKCa channels: proteomics analysis of synaptic protein complexes.
In every synapse, a large number of proteins interact with other proteins in order to carry out signaling and transmission in the central nervous system. In this study, we used interaction proteomics to identify novel synaptic protein interactions in mouse cortical membranes under native conditions. Using immunoprecipitation, immunoblotting, and mass ... spectrometry, we identified a number of novel synaptic protein interactions involving soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs), calcium-activated potassium channel (BKCa) alpha subunits, and dynamin-1. These novel interactions offer valuable insight into the protein-protein interaction network in intact synapses that could advance understanding of vesicle trafficking, release, and recycling.
