    Dev Biol 234:93-106. 2001
    ..Misexpression of mouse nkd1 in Drosophila antagonizes Wg function. The data suggest that the vertebrate Nkd-related proteins, similar to their fly counterpart, may act as inducible antagonists of Wnt signals...

    Genes Dev 15:658-71. 2001
    ..Our results suggest that Nkd acts directly through Dsh to limit Wg activity and thus determines how efficiently Wnt signals stabilize Armadillo (Arm)/beta-catenin and activate downstream genes...

    W Zeng
    Department of Developmental Biology, Howard Hughes Medical Institute, Beckman Center, Stanford University School of Medicine, California 94305, USA
    Nature 403:789-95. 2000
    ..Nkd may therefore link ion fluxes to the regulation of the potency, duration or distribution of Wnt signals. Signal-inducible feedback antagonists such as nkd may limit the effects of Wnt proteins in development and disease...

    Dev Biol 311:538-53. 2007

    J Biol Chem 277:49019-26. 2002
