Abstract
The microcephaly protein, Cep215, contributes to the engagement of duplicated centrioles in interphase. Now two distinct pools of Cep215 at centrosomes are identified, one bound to Cep68 and the other to pericentrin. Plk1-mediated degradation of Cep68 and separase-mediated cleavage of pericentrin release both pools of Cep215, thereby promoting centriole disengagement.
