Disrupting the spindle assembly checkpoint in the aurA mutant does not prevent neuroblast amplification, tumor formation or chromosome segregation.
Aurora A kinase activity contributes to phosphorylation of kinetochore substrates near poles and its inhibition results in chromosome misalignment and an increased incidence of erroneous kinetochore-MT attachments.
AurA and aPKC exert the spatiotemporal control of Lgl distribution to achieve unique cell polarity roles in distinct cell types.
Aurora A and B kinases directly phosphorylate Lgl to promote its mitotic relocalization.
Drosophila melanogaster aurora A phosphorylates the dynactin (show DCTN1 Proteins) subunit p150(glued (show DCTN1 Proteins)) on sites required for its association with the mitotic spindle.
One of the functions of Aurora A kinase is to direct centrosomal organization such that D-TACC complexed to the MSPS/XMAP215 microtubule-associated protein may be recruited, and thus modulate the behavior of astral microtubules.
Drosophila Aurora-A is required for centrosome maturation and actin-dependent asymmetric protein localization during mitosis.
Deletion mapping identifies a central domain of Aurora-A as essential for its centrosomal localization that is augmented by both the amino and the carboxyl terminal ends of the protein.

Aurora-A is essential for many crucial events during mitosis and phosphorylation of a series of substrates by Aurora-A at different stages of mitosis may promote diverse critical events in mitosis to maintain chromosome integrity in cells
Zebrafish Aurora-A is critically required for embryonic proliferation during development.
Although research biopsies were obtained on only a few patients, they did confirm pharmacodynamic effects of the drug. These effects though suggest inhibition of Aurora B (show AURKB Proteins) rather than Aurora A, which consistent with pre-clinical data that show dose-dependent effects on both

Our findings suggested that AURKA (rs911160) and AURKB (show AURKB Proteins) (rs2289590) polymorphisms could affect GC risk. Further validation studies in larger and multi-ethnical populations are needed to elucidate their functional impact on the development of GC
Possible models of regulation of Lck (show LCK Proteins) by Aurora-A during T cell activation are described in the review.
our study demonstrate that KCTD12 binds to CDC25B (show CDC25B Proteins) and activates CDK1 (show CDK1 Proteins) and Aurora A to facilitate the G2/M transition and promote tumorigenesis and that Aurora A phosphorylates KCTD12 at serine 243 to trigger a positive feedback loop, thereby potentiating the effects of KCTD12. Thus, the KCTD12-CDC25B (show CDC25B Proteins)-CDK1 (show CDK1 Proteins)-Aurora A axis has important implications for cancer diagnoses and prognoses.
Our findings showed novel regulatory mechanisms of p53 (show TP53 Proteins) in regulating Aurora-A gene expression in non-small cell lung carcinoma cells.
HIP2 (show UBE2K Proteins) regulates mitotic spindle alignment. SHIP2 (show INPPL1 Proteins) is expressed in G1 phase, whereas Aurora A kinase is enriched in mitosis. SHIP2 (show INPPL1 Proteins) binds Aurora A kinase and the scaffolding protein HEF1 (show NEDD9 Proteins) and promotes their basolateral localization at the expense of their luminal expression connected with cilia resorption.
Aurora kinase inhibitor CCT137690 induces necrosis-like death in pancreatic ductal adenocarcinoma cells, via RIPK1, RIPK3, and MLKL signaling.
our data indicate that hnRNP (show HNRNPC Proteins) Q1 is a novel trans-acting factor that binds to Aurora-A mRNA 5'-UTRs and regulates its translation, which increases cell proliferation and contributes to tumorigenesis in colorectal cancer
A central role of Aurora kinase A (AURKA) in promoting Epithelial-to-mesenchymal transition and cancer stem cell phenotypes via ALDH1A1 (show ALDH1A1 Proteins).
Aurora A and Plk4 (show PLK4 Proteins) are rate-limiting factors contributing to microtubule growth as the acentriolar oocyte resumes meiosis.
The high sequence similarity among the AURK family members has made discerning the individual kinase functions in meiosis challenging. Technical limitations in specifically targeting AURKB (show AURKB Proteins) or AURKC (show AURKC Proteins) using small-molecule inhibitors and compensatory abilities in single-knockout animals add to this challenge...proper regulation of AURKA expression is crucial for spindle formation in meiosis
CIP2A (show KIAA1524 Proteins) acts as a scaffold for CEP192-mediated microtubule organizing center assembly by recruiting Plk1 and aurora A during meiotic maturation in mouse oocytes
AURKA stabilizes MYC (show MYC Proteins) to promote tp53 (show TP53 Proteins)-altered liver tumor cell survival.
Bcl2l10 (show BCL2L10 Proteins), Tpx2 (show DAZL Proteins), and Aurka co-localized on the meiotic spindles, and Bcl2l10 (show BCL2L10 Proteins) was present in the same complex with Tpx2 (show DAZL Proteins).
Suppression of neuroendocrine and NEPC development by ICT was associated with dose-dependent inhibitory effects on abnormally elevated IL-6 (show IL6 Proteins)/STAT3 (show STAT3 Proteins) and Aurora kinase A in vitro and in vivo

Aurora-A may be a multifunctional kinase that plays pivotal regulatory roles in microtubule assembly during porcine oocyte meiotic maturation, fertilization and early embryonic mitosis
Aurora A stimulates the protein synthesis and promotes the meiotic resumption.

Plx1 promotes activation of Aurora A, most likely through TPX2.
Aurora-A kinase is required for astral microtubule polymerization and spindle microtubule flux during chromosome segregation.

Results suggest that phosphorylation of maskin (show TACC3 Proteins) by Aurora-A prevents meiosis II proteins from being produced during meiosis I.
The N-terminal non-catalytic domain of Aurora-A can localize to the centrosome in Xenopus egg extracts, while GFP fusions of either the N-terminal or catalytic domains are targeted to the centrosome in Xenopus XL2 cells.
Here we identify G205 in Xenopus Aurora A as a key determinant of both intrinsic activity and regulation by TPX2
The catalytic domain alone of Aurora-A is sufficient to restore spindle bipolarity; additional N-terminal sequences function in mitotic timing.
The protein encoded by this gene is a cell cycle-regulated kinase that appears to be involved in microtubule formation and/or stabilization at the spindle pole during chromosome segregation. The encoded protein is found at the centrosome in interphase cells and at the spindle poles in mitosis. This gene may play a role in tumor development and progression. A processed pseudogene of this gene has been found on chromosome 1, and an unprocessed pseudogene has been found on chromosome 10. Multiple transcript variants encoding the same protein have been found for this gene.
