Serine/threonine-protein kinase Aurora-3 (AUR3) is a plant homologue of the animal and yeast Aurora kinase. It associates with cytoskeletal structures that are necessary for cytokinesis and with the microtubule spindle [PMID: 16028112]. It is required for chromosome segregation in tobacco BY-2 cells [PMID: 17087760]. Arabidopsis AtAUR3 shows dot-like distribution on condensed chromosomes at prophase and then localises at the metaphase plate. At late anaphase, AtAUR3 is evenly localised on chromosomes [PMID: 16028112].
