193 (A) Wildtype BSEP-EYFP (BSEP-wt) and (B) BSEP-G374S-EYFP (green) were transfected in HEK293 cells. Login to comment
195 While expression of Na+ -K+ -ATPase was not significantly different (C), total (D) and plasma membrane expression (E) of BSEP was significantly higher (*) in cells transfected with mutant BSEP-G374S as compared to wildtype BSEP. Login to comment
196 Although G374S is associated with a severe cholestatic phenotype, there is no obvious trafficking defect. Login to comment
197 be a transition between BRIC-2 and PFIC-2 as shown for a patient compound heterozygous for p.I498T and c.2098delA [143] or siblings with the homozygous mutation p.G374S. Login to comment
200 While an inverse correlation between the amount of BSEP at the plasma membrane and the severity of phenotypes has been described for other mutations [144] p.G374S showed an increased membrane expression of BSEP (as compared to wildtype BSEP) despite the severity of the phenotype (Weissenberger, H&#e4;ussinger, Kubitz, unpublished) (Fig. 4).
