Novel liver‐specific organic anion transporter OAT7 that operates the exchange of sulfate conjugates for short chain fatty acid butyrate†

Abstract

OAT7 is the first liver-specific transporter among members of the organic anion transporters of SLC22 family. Our findings suggest a new class of substrates for organic anion transporters and provide evidence for the transport of anionic substances such as sulfate-conjugates in exchange for butyrate in hepatocytes.
