    题名: Identification of c-Fos as a mitotic phosphoprotein: regulation of c-Fos by Aurora-A

    摘要: The c-Fos has been implicated in the regulation of gene expression under a variety of stimuli. It is known that c-Fos undergoes protein phosphorylation, which may subsequently modulate diverse functions in cells. However, less is known about the role and phosphorylation status of c-Fos during mitosis. Here, we showed that c-Fos exhibited an electrophoretic mobility up-shift as detected by SDS-PAGE during mitosis, which is an indication of protein phosphorylation. Aurora-A, but not Aurora-B or -C, serves as one of the kinases catalyzing the mitotic phosphorylation of c-Fos. The mobility up-shift was partially abolished by introducing siRNA or a catalytically inactive form of Aurora-A. Moreover, ectopic expression of the wild type, but not the catalytically inactive form of Aurora-A resulted in the alteration of c-Fos complex formation, suggesting Aurora-A is engaged in the regulation of c-Fos protein-protein interaction. These findings imply that c-Fos may undergo cell cycle dependent phosphorylation, in which some kinases including Aurora-A play a role in catalyzing the post translational modification of c-Fos.
