Voltage-dependent proton-permeable channels are membrane proteins mediating a number of important physiological functions. Here we report the presence of a gene encoding Hv1 voltage-dependent, proton-permeable channels in two species of reef-building

The Hv1 proton channel is evidently unique among voltage sensor domain proteins in mediating an intrinsic ‘aqueous’ H+ conductance (GAQ). Mutation of a highly conserved ‘gating charge’ residue in the S4 helix (R1H) confers a resting-state H+

The Hv1 proton channel shares striking structural homology with fourth transmembrane helical segment-type voltage-sensor (VS) domains but manifests distinctive functional properties, including a proton-selective “aqueous” conductance and alloster

Hv1 proteins form a voltage-gated proton channel that is inhibited by extracellular Zn2+. De La Rosa et al find that extracellular Zn2+ is octahedrally coordinated by specific protein atoms and that Zn2+ occupancy modulates voltage sensor activation
