Proton-gated channels expressed by sensory neurons are of particular interest because low pH causes pain. Two proton-gated channels, acid-sensing ionic channel (ASIC) and dorsal root ASIC (DRASIC), that are members of the amiloride-sensitive ENaC/Degenerin family are known to be expressed by sensory neurons. ASIC-beta, an ASIC splice variant contains a unique N-terminal 172 aa, as well as unique 5' and 3' untranslated sequence. ASIC-beta, unlike ASIC and DRASIC, is found only in a subset of small and large diameter sensory neurons and is absent from sympathetic neurons or the central nervous system. ASIC-beta forms a functional channel with electrophysiological properties distinct from ASIC and DRASIC. The pH dependency and sensitivity to amiloride of ASIC-beta is similar to that described for ASIC, but unlike ASIC, the channel is not permeable to calcium, nor are ASIC-beta-mediated currents inhibited by extracellular calcium. The unique distribution of ASIC-beta suggests that it may play a specialized role in sensory neuron function.
