Sodium/bile acid cotransporter also known as the Na+-taurocholate cotransporting polypeptide (NTCP) or liver bile acid transporter (LBAT) is a protein that in humans is encoded by the SLC10A1 (solute carrier family 10 member 1) gene.[1][2]


Sodium/bile acid cotransporters are integral membrane glycoproteins that participate in the enterohepatic circulation of bile acids. Two homologous transporters are involved in the reabsorption of bile acids, one absorbing from the intestinal lumen, the bile duct, and the kidney with an apical localization (SLC10A2), and the other being found in the basolateral membranes of hepatocytes (SLC10A1; this protein).[1]

NTCP is a cell surface receptor necessary for the entry of Hepatitis B and Hepatitis D Virus.[3]
