Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables osmolarity-sensing monoatomic cation channel activity; sodium channel activity; and transmembrane transporter binding activity. Involved in osmosensory signaling pathway. Acts upstream of or within cellular homeostasis; response to bacterium; and sodium ion homeostasis. Located in glial cell projection. Is active in plasma membrane. Is expressed in heart and heart ventricle. Orthologous to human SCN7A (sodium voltage-gated channel alpha subunit 7).
