SLC22A9
Description
The SLC22A9 (solute carrier family 22 member 9) is a protein-coding gene located on chromosome 11.
Solute carrier family 22 member 9 is a protein that in humans is encoded by the SLC22A9 gene.
SLC22A9, also known as Organic anion transporter 7 (OAT7) or Organic anion/short-chain fatty acid exchanger, is a sodium-independent organic anion transporter. It exhibits high specificity for sulfated conjugates of xenobiotics and steroid hormones, such as estrone 3-sulfate (E1S) and dehydroepiandrosterone sulfate (DHEAS). SLC22A9 can transport the statin pravastatin and may contribute to its disposition into the hepatocytes when the function of OATPs is compromised. It is specifically activated by 3 to 5 carbons-containing short-chain fatty acids/SCFAs, including propionate (propanoate), butyrate (butanoate) and valerate (pentanoate). SLC22A9 may operate the exchange of sulfated organic components against short-chain fatty acids/SCFAs, in particular butanoate, at the sinusoidal membrane of hepatocytes.
SLC22A9 is also known as HOAT4, OAT4, OAT7, UST3H, ust3.
