Protein

Aurora kinase A-A

Gene

aurka-a

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Mitotic serine/threonine kinases that contributes to the regulation of cell cycle progression. Associates with the centrosome and the spindle microtubules during mitosis and plays a critical role in various mitotic events including the establishment of mitotic spindle, centrosome duplication, centrosome separation as well as maturation, chromosomal alignment, spindle assembly checkpoint, and cytokinesis. Phosphorylates numerous target proteins. Important for microtubule formation and/or stabilization.3 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.2 Publications
