CPAP-a gene mutated in primary microcephaly-is required for procentriole formation. Here we show that CPAP degradation and function is controlled by the poly(ADP-ribose) polymerase tankyrase 1. CPAP is PARsylated by tankyrase 1 in vitro and in vivo. Overexpression of tankyrase 1 leads to CPAP proteasomal degradation, preventing centriole duplication, whereas depletion of tankyrase 1 stabilizes CPAP in G1, generating elongated procentrioles and multipolarity. Tankyrase 1 localizes to centrosomes exclusively in G1, coinciding with CPAP degradation. Hence, tankyrase 1-mediated PARsylation regulates CPAP levels during the cell cycle to limit centriole elongation and ensure normal centrosome function.
