SLC10A1

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

Function
Sodium/bile acid is_associated_with::cotransporters are integral membrane glycoproteins that participate in the enterohepatic circulation of is_associated_with::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 (is_associated_with::SLC10A2), and the other being found in the basolateral membranes of hepatocytes (SLC10A1; this protein).

NTCP is a cell surface receptor necessary for the entry of hepatitis B and is_associated_with::hepatitis D virus.
