Voltage-gated hydrogen channel 1

Gene

Hvcn1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Mediates the voltage-dependent proton permeability of excitable membranes. Forms a proton-selective channel through which protons may pass in accordance with their electrochemical gradient. Proton efflux, accompanied by membrane depolarization, facilitates acute production of reactive oxygen species in phagocytosis.5 Publications

Enzyme regulationi

The dimers display cooperative channel gating. The channel activity is inhibited by zinc ions.4 Publications

The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position. Unlike other voltage-gated ion channels it lacks the pore domain.1 Publication
The C-terminal coiled coil region mediates homodimerization and cooperative channel gating. It is essential for normal subcellular localization.1 Publication
