Catalyzes the transport of the major hydrophobic bile salts, such as taurine and glycine-conjugated cholic acid across the canalicular membrane of hepatocytes in an ATP-dependent manner, therefore participates in hepatic bile acid homeostasis and consequently to lipid homeostasis through regulation of biliary lipid secretion in a bile salts dependent manner (PubMed:16332456, PubMed:22262466, PubMed:15791618, PubMed:18985798, PubMed:19228692, PubMed:20398791, PubMed:24711118, PubMed:29507376, PubMed:20010382, PubMed:32203132).

Transports taurine-conjugated bile salts more rapidly than glycine-conjugated bile salts (PubMed:16332456).

Also transports non-bile acid compounds, such as pravastatin and fexofenadine in an ATP-dependent manner and may be involved in their biliary excretion (PubMed:15901796, PubMed:18245269).

The uptake of taurocholate is inhibited by taurolithocholate sulfate with an IC50 of 9 µM (PubMed:16332456). Pravastatin competitively inhibits the transport of taurocholic acid (PubMed:18985798, PubMed:15901796). Cyclosporin A, glibenclamide, rifampicin and troglitazonestrongly competitively inhibit the transport activity of taurocholate (PubMed:18985798, PubMed:32203132). The canalicular transport activity of taurocholate is strongly dependent on canalicular membrane cholesterol content (PubMed:19228692). The uptake of taurocholate is increased by short- and medium-chain fatty acids (PubMed:20398791). Cholesterol increases transport capacity of taurocholate without affecting the affinity for the substrate (PubMed:24711118).7 Publications
