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:

Feed The World
1: It's Christmas time
There's no need to be afraid
At Christmas time
We let in light and we banish shade
And in our world of plenty
We can spread a smile of joy
Throw your arms around the world
At Christmas time
2: But say a prayer
Pray for the other ones
At Christmas time it's hard
But when you're having fun
There's a world outside your window
And it's a world of dread and fear
Where the only water flowing
Is the bitter sting of tears
And the Christmas bells that ring
There are the clanging chimes of doom
Well tonight thank God it's them instead of you
Feed the world
Let them know it's Christmas time
Feed the world
Do they know it's Christmas time at all?
3: And there won't be snow in Africa
This Christmas time
The greatest gift they'll get this year is life
Where nothing ever grows
No rain nor rivers flow
Do they know it's Christmas time at all?
Feed the world
Let them know it's Christmas time
Feed the world
Let them know it's Christmas time again
BRIDGE:
(Here's to you) raise a glass for everyone
(Here's to them) underneath that burning sun
Do they know it's Christmas time at all?
END: Feed the world
