Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables sodium:proton antiporter activity. Predicted to be involved in several processes, including microtubule cytoskeleton organization; regulation of protein modification process; and regulation of protein transport. Predicted to act upstream of or within proton transmembrane transport and sodium ion transmembrane transport. Part of transporter complex. Is active in membrane raft. Is expressed in genitourinary system. Human ortholog(s) of this gene implicated in spastic ataxia. Orthologous to human CHP1 (calcineurin like EF-hand protein 1).
