Polo-like kinase 4 is essential for centrosome duplication, but its hyperactivation causes supernumerary centrosomes. Here we report that polo-like kinase 4 is directly phosphorylated and activated by ...
The centrosome duplicates once in S phase. To determine whether there is a block in centrosome reduplication, we used a cell fusion assay to compare the duplication potential of unduplicated G1 ...
