DESCRIPTION

Also known as AURKA_HUMAN, AURKA, AIK, AIRK1, ARK1, AURA, AYK1, BTAK, IAK1, STK15, STK6. Mitotic serine/threonine kinase that contributes to the regulation of cell cycle progression (PubMed:11039908, PubMed:12390251, PubMed:17125279, PubMed:17360485, PubMed:18615013, PubMed:26246606). 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 (PubMed:14523000, PubMed:26246606). Required for normal spindle positioning during mitosis and for the localization of NUMA1 and DCTN1 to the cell cortex during metaphase (PubMed:27335426). Required for initial activation of CDK1 at centrosomes (PubMed:13678582, PubMed:15128871). Phosphorylates numerous target proteins, including ARHGEF2, BORA, BRCA1, CDC25B, DLGP5, HDAC6, KIF2A, LATS2, NDEL1, PARD3, PPP1R2, PLK1, RASSF1, TACC3, p53/TP53 and TPX2 (PubMed:11551964, PubMed:14702041, PubMed:15128871, PubMed:15147269, PubMed:15987997, PubMed:17604723, PubMed:18056443, PubMed:18615013). Regulates KIF2A tubulin depolymerase activity (PubMed:19351716). Important for microtubule formation and/or stabilization (PubMed:18056443). Required for normal axon formation (PubMed:19812038). Plays a role in microtubule remodeling during neurite extension (PubMed:19668197). 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 destabilizing p53/TP53 (PubMed:14702041). Phosphorylates its own inhibitors, the protein phosphatase type 1 (PP1) isoforms, to inhibit their activity (PubMed:11551964). Inhibits cilia outgrowth (By similarity). Required for cilia disassembly via phosphorylation of HDAC6 and subsequent deacetylation of alpha-tubulin (PubMed:17604723, PubMed:20643351). Regulates protein levels of the anti-apoptosis protein BIRC5 by suppressing the expression of the SCF(FBXL7) E3 ubiquitin-protein ligase substrate adapter FBXL7 through the phosphorylation of the transcription factor FOXP1 (PubMed:28218735). Part of a complex composed of NEDD9, AURKA and CTTN; within the complex NEDD9 acts as a scaffold protein and is required for complex formation (PubMed:24574519). Identified in a complex with AUNIP and NIN (PubMed:20596670). Interacts with FBXL7 (By similarity). Interacts with CPEB1, JTB, TACC1, TPX2, PPP2CA, as well as with the protein phosphatase type 1 (PP1) isoforms PPP1CA, PPP1CB and PPP1CC (PubMed:11551964, PubMed:14580337, PubMed:14603251, PubMed:15966895, PubMed:17229885, PubMed:18662907, PubMed:19357306, PubMed:19668197, PubMed:19801554, PubMed:21225229, PubMed:27837025). Interacts also with its substrates ARHGEF2, BORA, KIF2A, PARD3, and p53/TP53 (PubMed:14702041, PubMed:16890155, PubMed:17488622, PubMed:19351716, PubMed:19812038). Interaction with BORA promotes phosphorylation of PLK1 (By similarity). Interacts with CIMAP3 (PubMed:20643351). Interacts with GADD45A, competing with its oligomerization (PubMed:20460379). Interacts (via C-terminus) with AUNIP (via C-terminus) (PubMed:20596670). Interacts with FRY; this interaction facilitates AURKA-mediated PLK1 phosphorylation (PubMed:22753416). Interacts with SIRT2 (PubMed:17726514, PubMed:22014574). Interacts with MYCN; interaction is phospho-independent and triggers AURKA activation; AURKA competes with FBXW7 for binding to unphosphorylated MYCN but not for binding to phosphorylated MYCN (PubMed:27837025). Interacts with HNRNPU (PubMed:21242313, PubMed:25986610). Interacts with AAAS (PubMed:26246606). Interacts with KLHL18 and CUL3 (PubMed:23213400). Interacts with FOXP1 (PubMed:28218735). Interacts with HDAC6; AURKA-mediated phosphorylation of HDAC6 promotes deacetylation of alpha-tubulin (PubMed:17604723).
