The Ca2+:Cation Antiporter (CaCA) Family (TC 2.A.19)Proteins of the CaCA family are found ubiquitously, having been identified in animals, plants, yeast, archaea and widely divergent bacteria.All of the characterized animal proteins catalyze Ca2+:Na+ exchange although some also transport K+. The NCX1 plasma membrane protein exchanges 3 Na+ for 1 Ca2+. The E. coli ChaA protein catalyzes Ca2+:H+ antiport but may also catalyze Na+:H+ antiport. All remaining well-characterized members of the family catalyze Ca2+:H+ exchange.This model is generated from the calcium ion/proton exchangers of the CacA family [Transport and binding proteins, Cations and iron carrying compounds]. Length = 365
This alignment models a family of bacterial and archaeal proteins that is homologous, except for lacking a central region of ~ 250 amino acids and an N-terminal region of 100 residues, to a functionally proven potassium-dependent sodium-calcium exchanger of the rat.
>PF01699 Na_Ca_ex: Sodium/calcium exchanger protein; InterPro: 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 []. Ca2+ is moved into or out of the cytosol depending on Na+ concentration []. In humans and rats there are 3 isoforms; NCX1 NCX2 and NCX3 []. ; GO: 0055085 transmembrane transport, 0016021 integral to membrane; PDB: 3V5U_A 3V5S_A.
