PFAM accession number:PF01699
Interpro abstract (IPR004837): The sodium/calcium exchangers are a family of integral membrane proteins. This domain covers the integral membrane regions of these proteins. Sodium/calcium exchangers regulate intracellular Ca2+ concentrations in many cells; cardiac myocytes, epithelial cells, neurons retinal rod photoreceptors and smooth muscle cells [(PUBMED:1700476)]. Ca2+ is moved into or out of the cytosol depending on Na+ concentration [(PUBMED:1700476)]. In humans and rats there are 3 isoforms; NCX1 NCX2 and NCX3 [(PUBMED:8798769)].
GO process:transmembrane transport (GO:0055085)
GO component:integral component of membrane (GO:0016021)
