Abstract
The aim of this short review is to describe the contribution of Xenopus laevis egg extracts to the discovery and understanding of the regulation and function of the serine/threonine kinase Aurora-A. The power of these extracts to recapitulate cell cycle events makes them a precious tool to decipher complex biological processes at the molecular level, including the mechanisms that affect Aurora-A (post-translational modifications) and mechanisms in which Aurora-A plays a crucial role (bipolar spindle assembly). We focus on the results obtained in cell-free extracts, but we also give an updated overview of Aurora A functions found in other systems.
