Caption

An illustration shows the tether that links an ArcLight protein's fluorescent domain (green and gray) to its voltage-sensing domain (orange) in a neuron's membrane. Rice University scientists suggest in a new study that depolarization of the membrane moves the voltage-sensing domain, which in turn compresses the fluorescent protein and quenches it.
