SLC9A1 (Solute Carrier Family 9 Member A1) is a Protein Coding gene. Diseases associated with SLC9A1 include Lichtenstein-Knorr Syndrome and Myocardial Stunning. Among its related pathways are Glycosaminoglycan metabolism and Metabolism. SLC9A1 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.
