Its overexpression has been associated with genome instability and oncogenic transformation. The protein kinase D (PKD) family is an emerging therapeutic target of cancer. Aberrant PKD activation has been implicated in tumor growth and survival, yet the underlying mechanisms remain to be elucidated. This study identified, for the first time, a functional crosstalk between PKD2 and Aurora A kinase in cancer cells. The data demonstrate that PKD2 is catalytically active during the G₂-M phases of the cell cycle, and inactivation or depletion of PKD2 causes delay in mitotic entry due to downregulation of Aurora A, an effect that can be rescued by overexpression of Aurora A.
