Regulation of Plasma Membrane Localization of the Na⁺-Taurocholate Co-Transporting Polypeptide by Glycochenodeoxycholate and Tauroursodeoxycholate.

The present study suggests that GCDC triggers the retrieval of Ntcp from the basolateral membrane into the cytosol through an oxidative stress-dependent activation of Fyn. TUDC prevents the GCDC-induced Fyn activation and Ntcp retrieval through integrin-dependent activation of PKA.
