Function

Neuronal differentiation, ciliary formation or DNA damage repair. Studies suggest that is involved in neuronal connectivity and plasticity (25850036). Potential activity in quiescent and differentiated cells, is recruited to the basal body of the primary cilium, where in complex with APC it negatively regulates ciliary length, by destabilizing axonemal. Inhibition of APC-Cdc20 activity increases the ciliary length, while overexpression of Cdc20 suppresses cilium formation (25139956).
