DBF4 Antibody

Using both gain- and loss-of-function experiments, it was found that Xenopus Dbf4 inhibited canonical Wnt signaling. Depletion of endogenous Dbf4 did not disturb gastrulation movements or early organizer genes, but resulted in embryos with morphologically defective heart and eyes and suppressed cardiac markers. The function of Dbf4 in heart development appeared to be independent of its role in the cell cycle. Dbf4 interacted physically and functionally with Frodo, a context-dependent regulator of Wnt signaling.
