The SLC10 family of sodium/bile salt cotransporters contains over 50 members in animal, plant and bacterial species. In man, two well-characterized members and three orphan transporters are known. The Na+/taurocholate cotransporting polypeptide (NTCP; SLC10A1) and the apical sodium-dependent bile salt transporter (ASBT; SLC10A2) are critical components of the enterohepatic circulation of bile salts. NTCP and ASBT are cotransporters that mediate sodium-dependent, electrogenic uptake of mainly bile salts into hepatocytes (NTCP), biliary epithelial cells, ileal enterocytes and renal proximal tubular cells (ASBT).
