== 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 kinases have emerged as attractive targets for the design of anticancer drugs. Through structure-based virtual screening, novel pyrazole hit 8a was identified as Aurora kinase A inhibitor (IC(50) = 15.1 microM). X-ray cocrystal structure of 8a in complex with Aurora A protein revealed the C-4 position ethyl carboxylate side chain as a possible modification site for improving the potency. On the basis of this insight, bioisosteric replacement of the ester with amide linkage and changing the ethyl substituent to hydrophobic 3-acetamidophenyl ring led to the identification of 12w with a approximately 450-fold improved Aurora kinase A inhibition potency (IC(50) = 33 nM), compared to 8a. Compound 12w showed selective inhibition of Aurora A kinase over Aurora B/C, which might be due to the presence of a unique H-bond interaction between the 3-acetamido group and the Aurora A nonconserved Thr217 residue, which in Aurora B/C is Glu and found to sterically clash with the 3-acetamido group in modeling studies.
