      Background InformationMammalian NHE (Na+/H+ Exchanger) is an integral membrane protein that is known to regulate intracellular pH by removing a proton in exchange for an extracellular sodium ion. There are nine known isofoms of NHE. The best characterized is NHE1, involved not only in intracellular pH control, but cell-volume control, cytoskeletal organization, heart disease and cancer. Transport by the NHE plays a pivotal role in the damage caused to the human myocardium during and following a myocardial infarction, and it is considered to represent a key step in the oncogenic transformation of cancerous cells. NHE comprises an N-terminal membrane domain that transports ions, and a C-terminal cytoplasmic domain that regulates activity and mediates cytoskeletal interactions. NHE2 - NHE5 isoforms are localized to the plasma membrane but exhibit greater tissue-specificity. NH2 and NH3 are more highly expressed in the kidney and intestine. Structurally, a single transmembrane segment from NHE1 has been solved, and the structure of bacterial Na+/H+ antiporter NhaA has been elucidated.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P19634 # 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. Plays an important role in signal transduction.
      SIZE: 815 amino acids; 90763 Da
      SUBUNIT: Interacts with tescalcin, CHP and CHP2.
      SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
      TISSUE SPECIFICITY: Kidney and intestine.
      PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. & O-glycosylated.
      SIMILARITY: SwissProt: P19634 ## Belongs to the Na(+)/H(+) exchanger (TC 2.A.36.5.1) family.
      MISCELLANEOUS: Inhibited by amiloride and 5-amino-substituted derivatives and activated in a cooperative fashion by intracellular H(+). In quiescent cells upon growth factor stimulation, the apparent affinity for internal H(+) is increased, resulting in a persistent rise in cytoplasmic pH.
