In animal cells, centriole number is strictly controlled in order to guarantee faithful cell division and genetic stability, but the mechanism by which the accuracy of centrosome duplication is maintained is not fully understood. Here, we show that
CCDC84
constrains centriole number by modulating
APC
/C
Cdh1
-mediated HsSAS-6 degradation. More importantly,
CCDC84
acetylation oscillates throughout the cell cycle, and the acetylation state of
CCDC84
at lysine 31 is regulated by the deacetylase SIRT1 and the acetyltransferase NAT10. Deacetylated
CCDC84
is responsible for its centrosome targeting, and acetylated
CCDC84
promotes HsSAS-6 ubiquitination by enhancing the binding affinity of HsSAS-6 for Cdh1. Our findings shed new light on the function of (de)acetylation in centriole number regulation as well as refine the established centrosome duplication model.
