FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a Na+/H+ antiporter that is a member of the solute carrier family 9. The encoded protein is a plasma membrane transporter that is expressed in the kidney and intestine. This protein plays a central role in regulating pH homeostasis, cell migration and cell volume. This protein may also be involved in tumor growth. [provided by RefSeq, Sep 2011]
PHENOTYPE: Two-thirds of homozygous null mice die before weaning with reduced body weight, ataxia, a relatively mild stomach phenotype, and a postmortem appearance suggestive of death by a convulsive seizure. Homozygotes also display impaired fluid secretion and NaCl absorption in their parotid glands. [provided by MGI curators]
