The proper function of biological ion channels requires defined modes of control (gating).[1] Voltage gating is the response of the ionic flux through the channel pore upon a change of the membrane potential. Neuronal signal propagation relies on voltage-gated ion channels.Progress in the structural biology of voltage gated ion channels [2] and the design and functional studies [3] of voltagemodulated model channels helps in understanding voltage gating,[4] and is a first step towards the implantation of synthetic voltage-modulated channels into neurons. In a continuation of our studies on the implantation of synthetic gramicidin-hybrid channels into cells (trabecular meshwork cells,[5] CHO cells [6]), we turned to synthetic voltage-gated channels. Terminal-charged amphiphilic compounds,[7] can self-assemble into voltage-dependent pores and rigid push–pull rods [8] with permanent axial macrodipoles to give voltage-sensitive pores. Compared with these self-assembled pores, the channel-active β6, 3-helix of gramicidinA (gA) is structurally well defined.[9](Figure 1)
