[[http://www.uniprot.org/uniprot/ASIC1_CHICK ASIC1_CHICK]] Cation channel with high affinity for sodium, which is gated by extracellular protons and inhibited by the diuretic amiloride (By similarity).<ref>PMID:16002453</ref> [[http://www.uniprot.org/uniprot/TXP1_PSACA TXP1_PSACA]] Potently and selectively blocks the acid-sensing ion channel ASIC1a/ACCN2. The blockade is rapid and reversible. Psalmotoxin 1 loses its capacity to block ASIC1a/ACCN2 as soon as this subunit is associated with another member of the family (ASIC2a/ACCN1 or ASIC3/ACCN3). The toxin can distinguish between the two ASIC1/ACCN2 splice variants ASIC1a/ACCN2 and ASIC1b/ACCN2.<ref>PMID:10829030</ref>
