Recombinant Human Acid-sensing ion channel 2 (ASIC2), Truncated

Uniprot Id

Q16515

Target Species

Human

Target Name

ASIC2

Target Full Name

Acid-sensing ion channel 2

Target Function

Cation channel with high affinity for sodium, which is gated by extracellular protons and inhibited by the diuretic amiloride. Also permeable for Li(+) and K(+). Generates a biphasic current with a fast inactivating and a slow sustained phase. Heteromeric channel assembly seems to modulate.

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

Amiloride-sensitive sodium channel (TC 1.A.6) family, ASIC2 subfamily

Target Tissue Specificity

Brain and spinal cord. Isoform 1 is also detected in testis, liver, colon and ovary.

Target Background

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.
