Summaries for ASIC2 Gene

Entrez Gene Summary for ASIC2 Gene

  • 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]

GeneCards Summary for ASIC2 Gene

ASIC2 (Acid Sensing (Proton Gated) Ion Channel 2) is a Protein Coding gene. Among its related pathways are Ion channel transport and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include voltage-gated sodium channel activity and ligand-gated sodium channel activity. An important paralog of this gene is SCNN1G.
