Slc9a1 - solute carrier family 9 (sodium/hydrogen exchanger), member 1

Enables sodium:proton antiporter activity. Acts upstream of or within several processes, including regulation of pH; response to acidic pH; and sodium ion transport. Located in apical plasma membrane. Is expressed in several structures, including alimentary system; early conceptus; nervous system; oocyte; and sensory organ. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 19 and congestive heart failure. Orthologous to human SLC9A1 (solute carrier family 9 member A1).
