Yet, the precise mechanism by which TTX blocks voltage-gated sodium (Na V) channels is not fully understood. Here molecular dynamics simulations are used to elucidate how TTX blocks mammalian voltage-gated sodium (Nav) channels and why it fails to be effective for the bacterial sodium channel, Na V Ab.1B) in TTX block of Na V channels [5] and [8] . Thus, the guanidine group of TTX may interact with the outer charged ring more intimately, rather than protruding into the filter. Here the inhibition of Na V Ab and Na V 1.4 by TTX is examined in atomic detail using molecular dynamics (MD) simulations.
Voltage-gated sodium channels (Na v) are key components for nerve excitability. They initiate and propagate the action potential in excitable cells, throughout the central and peripheral nervous system, thus enabling a variety of physiological functions to be achieved.odium channels, other than epithelial Na + channels (ENaC) or sodium leak channels (NALCN), belong to the superfamily of voltage-gated ion channels, which all share the property of carrying ions between cellular compartments in response to membrane voltage stimulation (Stock et al., 2013).
