+== Function ==
+[https://www.uniprot.org/uniprot/AURKA_HUMAN AURKA_HUMAN] 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. Required for initial activation of CDK1 at centrosomes. Phosphorylates numerous target proteins, including ARHGEF2, BORA, BRCA1, CDC25B, DLGP5, HDAC6, KIF2A, LATS2, NDEL1, PARD3, PPP1R2, PLK1, RASSF1, TACC3, p53/TP53 and TPX2. Regulates KIF2A tubulin depolymerase activity. Required for normal axon formation. Plays a role in microtubule remodeling during neurite extension. Important for microtubule formation and/or stabilization. Also acts as a key regulatory component of the p53/TP53 pathway, and particularly the checkpoint-response pathways critical for oncogenic transformation of cells, by phosphorylating and stabilizing p53/TP53. Phosphorylates its own inhibitors, the protein phosphatase type 1 (PP1) isoforms, to inhibit their activity. Necessary for proper cilia disassembly prior to mitosis.<ref>PMID:9606188</ref> <ref>PMID:11039908</ref> <ref>PMID:11551964</ref> <ref>PMID:12390251</ref> <ref>PMID:13678582</ref> <ref>PMID:14523000</ref> <ref>PMID:15147269</ref> <ref>PMID:14990569</ref> <ref>PMID:15128871</ref> <ref>PMID:14702041</ref> <ref>PMID:15987997</ref> <ref>PMID:18056443</ref> <ref>PMID:17604723</ref> <ref>PMID:17360485</ref> <ref>PMID:18615013</ref> <ref>PMID:19812038</ref> <ref>PMID:19351716</ref> <ref>PMID:19668197</ref> <ref>PMID:19357306</ref> <ref>PMID:20643351</ref> <ref>PMID:17125279</ref>

+== Publication Abstract from PubMed ==
+Aurora-A is an oncogenic kinase essential for mitotic spindle assembly. It is activated by phosphorylation and by the microtubule-associated protein TPX2, which also localizes the kinase to spindle microtubules. We have uncovered the molecular mechanism of Aurora-A activation by determining crystal structures of its phosphorylated form both with and without a 43 residue long domain of TPX2 that we identified as fully functional for kinase activation and protection from dephosphorylation. In the absence of TPX2, the Aurora-A activation segment is in an inactive conformation, with the crucial phosphothreonine exposed and accessible for deactivation. Binding of TPX2 triggers no global conformational changes in the kinase but pulls on the activation segment, swinging the phosphothreonine into a buried position and locking the active conformation. The recognition between Aurora-A and TPX2 resembles that between the cAPK catalytic core and its flanking regions, suggesting this molecular mechanism may be a recurring theme in kinase regulation.
