HHsearch alignment for GI: 254780368 and conserved domain: cd01988

>cd01988 Na_H_Antiporter_C The C-terminal domain of a subfamily of Na+ /H+ antiporter existed in bacteria and archea . Na+/H+ exchange proteins eject protons from cells, effectively eliminating excess acid from actively metabolising cells. Na+ /H+ exchange activity is also crucial for the regulation of cell volume, and for the reabsorption of NaCl across renal, intestinal, and other epithelia. These antiports exchange Na+ for H+ in an electroneutral manner, and this activity is carried out by a family of Na+ /H+ exchangers, or NHEs, which are known to be present in both prokaryotic and eukaryotic cells. These exchangers are highly-regulated (glyco)phosphoproteins, which, based on their primary structure, appear to contain 10-12 membrane-spanning regions (M) at the N-terminus and a large cytoplasmic region at the C-terminus. The transmembrane regions M3-M12 share identity wit h other members of the family. The M6 and M7 regions are highly conserved. Thus, this is thought to be the regio
