Protein that plays a role in the inhibition of canonical Wnt signaling pathway (By similarity). May be involved in neuronal migration during development of the cerebral neocortex (PubMed:16278297). Involved in the control of ciliogenesis and ciliary length (By similarity). Interacts with DVL1, DVL2 and DVL3. Localizes to the ciliary axoneme and to mitotic spindle fibers in a cell-cycle-dependent manner. Expressed in hair cells of the inner ear.
