CYLD tidies up dishevelled signaling.
An increasing number of cellular signaling pathways utilize protein ubiquitination for activation of signaling cascades. In this issue of Molecular Cell, Maurice and colleagues demonstrate that nondegradative Lys63-linked polyubiquitin chains modulate Dishevelled (Dvl) activity upstream in the Wnt/beta-catenin signaling pathway.
