Background	Currents measured from voltage-gated proton channels were detected long before the channel (HVCN1, also known as Hv1 and VSOP) was cloned. HVCN1 has four membrane spanning domains and intracellular N- and C-termini. Interesting aspects of HVCN1 is that unlike its voltage-gated ion channel counterparts, it has no pore domain. Also, functional HVCN1 channels are formed by dimers where each monomer has its own conducting pore, each with its own voltage sensor (voltage sensing occurs similarly to other voltage-gated ion channels). The fundamental role of HVCN1 is to pump out protons, thereby increasing the intracellular pH. The channel is exclusively selective for H+ and opens upon membrane depolarization, although its open state hugely depends on the pH on both sides of the membrane. Its role is best described in leukocytes where phosphorylation via PKC on a Thr residue potentiates the activity of the channel and increases its open state, thereby increasing the H+ current across the membrane, in this manner mediating optimal NADPH-oxidase (whose optimal activity is at pH 7.5) required for the production of reactive oxygen species (ROS) necessary for phagocytosis to occur. Apart from leukocytes, HVCN1 is also expressed in basophils where its activation mediates histamine release. In B cells, it maintains optimal signaling, such that ROS production is maintained high. HVCN1 was found to regulate human spermatozoa activation. Finally, in the airway mucosa, where it regulates pH, channel gating there, is mostly mediated by differences in pH across the membrane as opposed to the membrane potential.
