Solute carrier family 22 member 19 (Slc22a19)

Sodium-independent organic anion transporter which shows high specificity for estrone sulfate, dehydroepiandrosterone sulfate, and the mycotoxin ochratoxin A (OTA) (PubMed:15068970, PubMed:16150593). Transport of OTA is recommended by estrone sulfate and probenecid, and to a lesser extent by 2,4- dichlorophenoxyacetic acid (2,4-D) and salicylate (PubMed:15068970).

Transport of estrone sulfate is inhibited by several steroid sulfate conjugates such as dehydroepiandrosterone sulfate, alpha-naphthyl sulfate, beta- estradiol sulfate, 4-methylumbelliferyl sulfate and p-nitrophenyl sulfate (but not minoxidil sulfate) (PubMed:16150593). .
