Disease

[NTCP_HUMAN] The disease is caused by variants affecting the gene represented in this entry.

Function

[NTCP_HUMAN] As a major transporter of conjugated bile salts from plasma into the hepatocyte, it has a key role in the enterohepatic circulation of bile salts necessary for the solubilization and absorption of dietary fat and fat-soluble vitamins. It exhibits broad substrate specificity and transports various non-bile acid organic compounds as well. It is strictly dependent on the extracellular presence of sodium. Able to transport taurocholate, cholate, and the non-bile acid estron sulfate (PubMed:14660639, PubMed:24867799).^{[1] [2]} (Microbial infection) Acts as a receptor for hepatitis B virus.^[3]
