Any process that modulates the frequency, rate or extent of action potential creation, propagation or termination. This typically occurs via modulation of the activity or expression of voltage-gated ion channels. [ https://www.worldcat.org/search?q=bn%3A978-0-07-139011-8 GOC:go_curators GOC:dph GOC:tb GOC:dos ]
Term information
The ion channels through which current flows during an action potential should be annotated to the process 'action potential'. Gene products involved in modulating the characteristics of an action potential via changing the expression levels or the activity of these channels (e.g. modulating their kinetics or voltage sensitivity) should be annotated to this regulation term.
