description Wnt signaling is a major player during development and its misregulation often leads to disease, especially cancer. The negative feedback Wnt regulator homologs, Nkd1 and Nkd2, have been shown to inhibit Wnt signaling during development, and current evidence suggests that Nkds degrade Dvl proteins to antagonize Wnt signaling. Here, we demonstrate that during early zebrafish development Nkd1 does not alter either endogenous or exogenous levels of Dvl2. Furthermore, Dvl2 does not affect the levels of Nkd1. Cumulatively, these results demonstrate that Dvl2 is a ubiquitous and stable protein and that Nkds may not always function to degrade Dvl proteins as a method of inhibiting Wnt signaling.
