    Summary
    Predicted to enable ligand-gated sodium channel activity. Involved in cellular response to water stimulus; drinking behavior; and liquid clearance, open tracheal system. Predicted to be integral component of membrane. Predicted to be integral component of plasma membrane. Is expressed in Kolbchen; gustatory system; primary trachea; and tracheal tip cell. Orthologous to several human genes including ASIC1 (acid sensing ion channel subunit 1) and ASIC4 (acid sensing ion channel subunit family member 4).
