19. Biochemical analysis of P4-ATPase mutations identified in patients with progressive familial intrahepatic cholestasis PMID: 23060447
20. Sequence analysis of the genes identified 27% cholestasis subjects with missense, nonsense, deletion, and splice site variants associated with disease phenotypes based on the type of mutation in the JAG1, ATP8B1, ABCB11, or ABCB4 genes. PMID: 20683201
21. results unveil a new paradigm whereby Atp8b1 is a cardiolipin importer whose capacity to remove cardiolipin from lung fluid is exceeded during inflammation or when Atp8b1 is defective PMID: 20852622
22. facilitating diagnosis and elucidating the differing consequences of ATP8B1 and ABCB11 mutations in progressive familial intrahepatic cholestasis PMID: 20447715
23. Data identified three novel mutations in BSEP, one novel mutation in MDR3, and one heterozygous mutation in ATP8B1 in PFIC patients. PMID: 20414253
24. We now report evidence that heterozygous genetically determined alteration of ATP8B1 (encoding FIC1) may also represent a risk factor for transient neonatal cholestasis. PMID: 20216097
25. critical role in apical membrane organization that is unrelated to its presumed aminophospholipid translocase activity PMID: 20512993
26. ATP8B1 gene mutations play an important role in Chinese patients with progressive intrahepatic cholestasis and low gamma-glutamyltransferase. The linked mutation P209T and IVS6+5G>T is a hot mutation in the Chinese population. PMID: 20038848
27. Progressive familial intrahepatic cholestasis types 1 & 2 differ clinically, biochemically, and histologically at presentation and/or during the disease course. A small proportion of normal-GGT PFIC is likely not due to ATP8B1 or ABCB11 mutations. PMID: 20232290
28. Findings support the hypothesis that hepatocyte FIC1 enhances FXR signaling via a PKCzeta-dependent signaling pathway. PMID: 19809379

33. Coexpression with CDC50 proteins resulted in relocalization of ATP8B1 from the endoplasmic reticulum to the plasma membrane. In the plasma membrane, ATP8B1 functions as a flippase for phosphatidylserine. PMID: 17948906
34. FIC1 signals to FXR via PKC zeta. FIC1-related liver disease is likely related to downstream effects of FXR on bile acid homeostasis. PMID: 18668687
