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. 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 (By similarity). Necessary for proper cilia disassembly prior to mitosis (By similarity). Interacts with SIRT2 (By similarity).By similarity

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Enzyme regulationi

Activation of CDK1, appears to be an upstream event of AURKA activation. Phosphatase inhibitor-2 (PPP1R2) and TPX2 act also as activators. Inactivated by the G2 checkpoint. Inhibited by GADD45A and p53/TP53, and through dephosphorylation by protein phosphatase type 1 (PP1). MLN8054 is also a potent and selective inhibitor (By similarity). Activated during the early phase of cilia disassembly in the presence of FBXL7 and PIFO (By similarity).By similarity

Post-translational modificationi

Activated by phosphorylation at Thr-288; this brings about a change in the conformation of the activation segment. Phosphorylation at Thr-288 varies during the cell cycle and is highest during M phase. Autophosphorylated at Thr-288 upon TPX2 binding. Thr-288 can be phosphorylated by several kinases, including PAK and PKA. Protein phosphatase type 1 (PP1) binds AURKA and inhibits its activity by dephosphorylating Thr-288 during mitosis. Phosphorylation at Ser-342 decreases the kinase activity.
Ubiquitinated by CHFR, leading to its degradation by the proteasome. Ubiquitinated by the anaphase-promoting complex (APC), leading to its degradation by the proteasome. Ubiquitinated by the E3 ubiquitin-protein ligase complex SCF(FBXL7) during mitosis, leading to its degradation by the proteasome (By similarity).By similarity

Interacts with GADD45A, competing with its oligomerization (By similarity). Interacts (via C-terminus) with AUNIP (via C-terminus) (By similarity). Identified in a complex with AUNIP and NIN (By similarity). Interacts with FRY; this interaction facilitates AURKA-mediated PLK1 phosphorylation (By similarity).By similarity
