摘要：
To isolate the murine Na+/taurocholate cotransporting polypeptide (Ntcp), we screened a mouse liver cDNA library and identified Ntcp1, encoding a 362 amino acid protein and Ntcp2, encoding a 317 amino acid protein which had a shorter C-terminal end. Both isoforms mediated saturable Na+-dependent transport of taurocholate when expressed in Xenopus laevis oocytes. Analysis of the gene revealed that Ntcp2 is produced by alternative splicing where the last intron is retained. (C) 1999 Elsevier Science B.V. All rights reserved.
