    Nature 463:507-12. 2010
    ..Our results have implications for the mechanism of the mammalian VKOR and explain how mutations can cause resistance to the VKOR inhibitor warfarin, the most commonly used oral anticoagulant...

    Howard Hughes Medical Institute, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA
    Mol Cell 26:511-21. 2007
    ..Our data show that the plug domain is required to maintain a closed state of the channel and suggest a mechanism for channel gating...

    Sol Schulman
    Department of Cell Biology, Harvard Medical School, Howard Hughes Medical Institute, 240 Longwood Avenue, Boston, MA 02115, USA
    Proc Natl Acad Sci U S A 107:15027-32. 2010
    ..Taken together, our results demonstrate that human VKOR employs the same electron transfer pathway as its bacterial homologs and that VKORs generally prefer membrane-bound Trx-like redox partners...

    Jiqing Ye
    Howard Hughes Medical Institute, Harvard Medical School, Boston, Massachusetts 02115, USA
    J Biol Chem 282:34945-51. 2007
    ..On the basis of structural similarity to the zinc fingers in Npl4 and Vps36, we propose that the N-terminal zinc finger of thioredoxin-2 mediates protein-protein interactions, possibly with its substrates or chaperones...
