CC -!- FUNCTION: Involved in the renal elimination of endogenous and exogenous
CC organic anions. Functions as organic anion exchanger when the uptake of
CC one molecule of organic anion is coupled with an efflux of one molecule
CC of endogenous dicarboxylic acid (glutarate, ketoglutarate, etc).
CC Mediates the sodium-independent uptake of 2,3-dimercapto-1-
CC propanesulfonic acid (DMPS), 9-(2-phosphonylmethoxyethyl) guanine
CC (PMEG), 9-(2-phosphonylmethoxyethyl) diaminopurine (PMEDAP), ochratoxin
CC (OTA), acyclovir (ACV), 3'-azido-3-'deoxythymidine (AZT), cimetidine
CC (CMD) and edaravone sulfate. Mediates the sodium-independent uptake of
CC p-aminohippurate (PAH), cidofovir, adefovir, 2,4-dichloro-
CC phenoxyacetate (2,4-D), hippurate (HA), indoleacetate (IA), indoxyl
CC sulfate (IS) and 3-carboxy-4-methyl-5-propyl-2-furanpropionate (CMPF).
CC PAH uptake is inhibited by p-chloromercuribenzenesulphonate (PCMBS),
CC diethyl pyrocarbonate (DEPC), indomethacin, sulindac, diclofenac,
CC carprofen, okadaic acid, benzothiazolylcysteine (BTC), S-
CC chlorotrifluoroethylcysteine (CTFC), cysteine S-conjugates S-
CC dichlorovinylcysteine (DCVC), furosemide, steviol, phorbol 12-myristate
CC 13-acetate (PMA), calcium ionophore A23187, benzylpenicillin,
CC bumetamide, losartan, phenol red, urate and alpha-ketoglutarate (By
CC similarity). PAH uptake is inhibited by glutarate and probenecid.
