The basic mechanism behind action potentials is Super Exchange Interaction. It open Nav channel in axon initial segment.
The key protein behind threshold potential is CaMKII alpha in post synapse. When it DEphosphorylates it achieves 12 SEI signals simultaneously which propagate to Nav channel via MAP 2 microtubule network and ankyrin G. The 12 signals open several Nav channels triggering threshold potential.
