CRYSTAL STRUCTURE OF AURORA-2, AN ONCOGENIC SERINE-THREONINE KINASECRYSTAL STRUCTURE OF AURORA-2, AN ONCOGENIC SERINE-THREONINE KINASE
Structural highlights
Function[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.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedAurora-2 is a key member of a closely related subgroup of serine/threonine kinases that plays important roles in the completion of essential mitotic events. Aurora-2 is oncogenic and amplified in various human cancers and could be an important therapeutic target for inhibitory molecules that would disrupt the cell cycle and block proliferation. We report the first crystal structure of Aurora-2 kinase in complex with adenosine. Analysis of residues in the active site suggests differences with structurally and biologically related protein kinases. The activation loop, which contains residues specific to the Aurora family of kinases, has a unique conformation. These results provide valuable insight into the design of selective and highly potent ATP-competitive inhibitors of the Aurora kinases.
