Defects in this gene are a cause of congenital secretory sodium diarrhea. Pseudogenes of this gene exist on chromosomes 10 and 22. [provided by RefSeq, Mar 2016]. * **UniProt Summary**: Involved in pH regulation to eliminate acids generated by active metabolism or to counter adverse environmental conditions. Major proton extruding system driven by the inward sodium ion chemical gradient (PubMed:26358773). Plays an important role in signal transduction. {ECO:0000269|PubMed:26358773}. |Na H Exchanger| |potassium:proton antiporter activity| |sodium:proton antiporter activity| |sodium ion import across plasma membrane| |brush border| |brush border membrane| |inorganic ion import across plasma membrane| |inorganic cation import across plasma membrane| |regulation of intracellular pH| |PDZ domain binding| |sodium ion transmembrane transport| |regulation of cellular pH| |import across plasma membrane| |regulation of pH| |cellular monovalent inorganic cation homeostasis| |monovalent inorganic cation homeostasis| |proton transmembrane transport| |sodium ion transport| |potassium ion transmembrane transport| |potassium ion transport| |anion transmembrane transport| |apical plasma membrane| |monovalent inorganic cation transport| |inorganic cation transmembrane transport| |anion transport| |cation transmembrane transport| |cell surface| |cellular cation homeostasis| |metal ion transport| |cellular ion homeostasis| |inorganic ion transmembrane transport| |import into cell| |cation homeostasis| |inorganic ion homeostasis| |cellular chemical homeostasis| |ion homeostasis| |cation transport| |cellular homeostasis| |ion transmembrane transport| |chemical homeostasis| |transmembrane transport| |ion transport| |homeostatic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp531|THZ1 0.06μM R08 exp531]]|-2.03| |[[:results:exp352|Dexamethasone 0.006 to 0.015μM on day4 R07 exp352]]|-1.93| |[[:results:exp426|FBS-Wisent 0.1 R07 exp426]]|-1.87| |[[:results:exp359|FK-506 30μM R07 exp359]]|-1.86| |[[:results:exp460|BML-284 0.09μM R08 exp460]]|-1.84| |[[:results:exp372|Ibrutinib 1μM R07 exp372]]|-1.74| |[[:results:exp21|MLN-4924 0.2μM R00 exp21]]|-1.7| |[[:results:exp526|Sulforaphane 9μM R08 exp526 no dilution day6]]|1.96| No correlation found to any other genes in chemogenomics.
