The anion exchanger family (TC# 2.A.31, also named bicarbonate transporter family) is a member of the large APC superfamily of secondary carriers. [1] Members of the AE family are generally responsible for the transport of anions across cellular barriers, although their functions may vary. All of them exchange bicarbonate. Characterized protein ...
All functionally characterized members of the APC superfamily use cation symport for substrate accumulation except for some members of the AE family which frequently use anion:anion exchange. All new entries contain the two 5 or 7 TMS repeat units characteristic of the APC superfamily, sometimes with extra TMSs at the ends likely the result of ...
Band 3 anion transport protein, also known as anion exchanger 1 (AE1) or band 3 or solute carrier family 4 member 1 (SLC4A1), is a protein that is encoded by the SLC4A1 gene in humans. Band 3 anion transport protein is a phylogenetically -preserved transport protein responsible for mediating the exchange of chloride (Cl − ) with bicarbonate ...
Pendrin is an anion exchange protein that in humans is encoded by the SLC26A4 gene (solute carrier family 26, member 4). [5] [6] Pendrin was initially identified as a sodium-independent chloride-iodide exchanger [7] with subsequent studies showing that it also accepts formate and bicarbonate as substrates.
Structure of the orthosilicate anion SiO 4− 4. A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO (4-2x)− 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO 4− 4 (x = 0), metasilicate SiO 2− 3 (x = 1), and pyrosilicate Si 2 O 6− 7 (x = 0.5 ...
It is usually followed by anion-exchange chromatography using 6 molar HCl as eluant. A cation-exchange resin column (Dowex-50 exchange column) treated with ammonium salts is then used to separate fractions containing elements 99, 100 and 101.
Multidrug resistance-associated protein 6 (MRP6) also known as ATP-binding cassette sub-family C member 6 (ABCC6) and multi-specific organic anion transporter E (MOAT-E) is a protein that in humans is encoded by the ABCC6 gene. [5] [6] [7] The protein encoded by the ABCC6 gene is a member of the superfamily of ATP-binding cassette (ABC ...
The exact mechanisms of anion transfer by UCPs are not known. [7] UCPs contain the three homologous protein domains of MACPs. Although it was originally thought to play a role in non-shivering thermogenesis, obesity, diabetes and atherosclerosis, it now appears that the main function of UCP2 is the control of mitochondria-derived reactive ...
