Protein Information (annotations from UniProt)

Database IDHIV0000026
UniProt IDQ9UHC3
Primary gene name(s)ASIC3
Synonym gene name(s)ACCN3, SLNAC1, TNAC1
Protein nameAcid-sensing ion channel 3
Protein functionCation channel with high affinity for sodium, which is gated by extracellular protons and inhibited by the diuretic amiloride. Generates a biphasic current with a fast inactivating and a slow sustained phase. In sensory neurons is proposed to mediate the pain induced by acidosis that occurs in ischemic, damaged or inflamed tissue. May be involved in hyperalgesia. May play a role in mechanoreception. Heteromeric channel assembly seems to modulate channel properties. {ECO:0000269|PubMed:9744806, ECO:0000269|PubMed:9886053}.
Subcellular locationCell membrane {ECO:0000250};
Multi-pass membrane protein {ECO:0000250}. Cytoplasm {ECO:0000250}. Note=Cell surface expression may be stabilized by interaction with LIN7B and cytoplasmic retention by interaction with DLG4. In part cytoplasmic in cochlea cells, By similarity. {ECO:0000250}.
