Band 3

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 in humans is encoded by the SLC4A1 gene.

Band 3 anion transport protein is a phylogenetically preserved transport protein responsible for mediating the exchange of chloride (Cl⁻) for bicarbonate (HCO₃⁻) across a plasma membrane. Functionally similar members of the AE clade are AE2 and AE3.

Function

This is present in the α-intercalated cells of the collecting ducts of the nephron. these are the main acid secreting cells of the kidney. They generate hydrogen ions and bicarbonate ions from carbon dioxide and water - a reaction catalysed by Carbonic anhydrase. The hydrogen ions are pumped into the collecting duct tubule by vacuolar H⁺ ATPase, the apical proton pump, which thus excretes acid into the urine. kAE1 exchanges bicarbonate for chloride on the basolateral surface, essentially returning bicarbonate to the blood. Here it performs two functions:

+/- (band)

+/-, or Plus/Minus, is an American indietronic band formed in 2001. The band makes use of both electronic and traditional instruments, and has sought to use electronics to recreate traditional indie rock song forms and instrumental structures. The group has released two albums on each of the American indie labels Teenbeat Records and Absolutely Kosher, and their track "All I do" was prominently featured in the soundtrack for the major film Wicker Park. The group has developed a devoted following in Japan and Taiwan, and has toured there frequently. Although many artists append bonus tracks onto the end of Japanese album releases to discourage purchasers from buying cheaper US import versions, the overseas versions of +/- albums are usually quite different from the US versions - tracklists can be rearranged, artwork with noticeable changes is used, and tracks from the US version can be replaced as well as augmented by bonus tracks.
