Amiloride-sensitive cation channel 1, neuronal
ASIC2, ASIC2a, BNC1, Acid-sensing ion channel 2, ACCN1
This gene encodes a member of the degenerin/epithelial sodium channel (DEG/ENaC) superfamily. The members of this family are amiloride-sensitive sodium channels that contain intracellular N and C termini, 2 hydrophobic transmembrane regions, and a large extracellular loop, which has many cysteine residues with conserved spacing. The member encoded by this gene may play a role in neurotransmission. In addition, a heteromeric association between this member and acid-sensing (proton-gated) ion channel 3 has been observed to co-assemble into proton-gated channels sensitive to gadolinium. Alternative splicing has been observed at this locus and two variants, encoding distinct isoforms, have been identified. [provided by RefSeq, Feb 2012] (from

The results showed that there was a significant increase in the mean relative optical density of ASIC2 and ASIC3 but not ASIC1a in the lining epithelium and glandular tubes of gastric mucosa in patients with Henoch-Schonlein purpura.
