Abstract
Novel members of the amiloride-sensitive Na+ channel/ degenerin family of ion channels were discovered recently. With the cloning of four mammalian H(+)-gated cation channel subunits, the first members of a novel class of ligand-gated cation channels were identified. H(+)-gated cation channel subunits are expressed in the central and peripheral nervous system. In sensory neurones, they are thought to be involved in the perception of pain that accompanies tissue acidosis.
