ACCN3 (ASIC3) belongs to the degenerin/epithelial sodium channel (DEG/ENaC) protein family. It is known to function as an acid sensor, as well as a sensor of acidic and inflammatory pain. It is also known to enhance H+ gated currents in neurons. ASIC3 has been implicated in ischemic pain and hyperalgesia. Rabbit Anti-ACCN3 antibody recognizes human, mouse, rat, bovine, and canine ACCN3.
Immunogen
Synthetic peptide directed towards the N terminal region of human ACCN3
Application
Rabbit Anti-ACCN3 antibody is suitable for western blot (2.5 μg/ml) and IHC (4-8 μg/ml) applications.
Biochem/physiol Actions
ACCN3 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, two hydrophobic transmembrane regions, and a large extracellular loop, which has many cysteine residues with conserved spacing. ACCN3 encodes a member that is an acid sensor and may play an important role in the detection of lasting pH changes. In addition, a heteromeric association between this member and ACCN1 has been observed as proton-gated channels sensitive to gadolinium.

Acid-sensing ion channel 3 (ASIC3) is highly expressed on sensory neurons that innervate heart and skeletal muscle and, therefore, is proposed to detect lactic acidosis and to transduce angina and muscle ischemic pain. A difficulty with this idea is that

The acid-sensing ion channels (ASICs) form cation channels that are transiently activated by extracellular protons. They are expressed in dorsal root ganglia (DRG) neurons and in the periphery where they play a function in nociception and mechanosensation. Previous studies showed
Acid-sensing ion channels (ASICs) are cationic channels activated by extracellular acidosis that are expressed in both central and peripheral nervous systems. Although peripheral ASICs seem to be natural sensors of acidic pain (e.g., in inflammation, ischaemia, lesions or tumours), a
