Function

Serine/threonine-protein kinase component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis (PubMed:11516652, PubMed:12925766, PubMed:14610074, PubMed:14722118, PubMed:29449677). The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly (PubMed:11516652, PubMed:12925766, PubMed:14610074, PubMed:14722118, PubMed:26829474). Involved in the bipolar attachment of spindle microtubules to kinetochores and is a key regulator for the onset of cytokinesis during mitosis (PubMed:15249581). Required for central/midzone spindle assembly and cleavage furrow formation (PubMed:12458200, PubMed:12686604). Key component of the cytokinesis checkpoint, a process required to delay abscission to prevent both premature resolution of intercellular chromosome bridges and accumulation of DNA damage: phosphorylates CHMP4C, leading to retain abscission-competent VPS4 (VPS4A and/or VPS4B) at the midbody ring until abscission checkpoint signaling is terminated at late cytokinesis (PubMed:22422861, PubMed:24814515). AURKB phosphorylates the CPC complex subunits BIRC5/survivin, CDCA8/borealin and INCENP (PubMed:11516652, PubMed:12925766, PubMed:14610074). Phosphorylation of INCENP leads to increased AURKB activity (PubMed:11516652, PubMed:12925766, PubMed:14610074). Other known AURKB substrates involved in centromeric functions and mitosis are CENPA, DES/desmin, GPAF, KIF2C, NSUN2, RACGAP1, SEPTIN1, VIM/vimentin, HASPIN, and histone H3 (PubMed:11756469, PubMed:11784863, PubMed:11856369, PubMed:12689593, PubMed:14602875, PubMed:16103226, PubMed:21658950). A positive feedback loop involving HASPIN and AURKB contributes to localization of CPC to centromeres (PubMed:21658950). Phosphorylation of VIM controls vimentin filament segregation in cytokinetic process, whereas histone H3 is phosphorylated at 'Ser-10' and 'Ser-28' during mitosis (H3S10ph and H3S28ph, respectively) (PubMed:11784863, PubMed:11856369). AURKB is also required for kinetochore localization of BUB1 and SGO1 (PubMed:15020684, PubMed:17617734). Phosphorylation of p53/TP53 negatively regulates its transcriptional activity (PubMed:20959462). Key regulator of active promoters in resting B- and T-lymphocytes: acts by mediating phosphorylation of H3S28ph at active promoters in resting B-cells, inhibiting RNF2/RING1B-mediated ubiquitination of histone H2A and enhancing binding and activity of the USP16 deubiquitinase at transcribed genes (By similarity). Acts as an inhibitor of CGAS during mitosis: catalyzes phosphorylation of the N-terminus of CGAS during the G2-M transition, blocking CGAS liquid phase separation and activation, and thereby preventing CGAS-induced autoimmunity (PubMed:33542149). Phosphorylates KRT5 during anaphase and telophase (By similarity). Phosphorylates ATXN10 which promotes phosphorylation of ATXN10 by PLK1 and may play a role in the regulation of cytokinesis and stimulating the proteasomal degradation of ATXN10 (PubMed:25666058).

Activity summary

Aurora B also known as Aurora kinase B or AURKB is a serine/threonine protein kinase with a molecular mass of approximately 39 kDa. This protein expresses across various cell types and tissues playing a critical role during cell division. It localizes to the centromeres during early mitosis and later associates with the central spindle and midbody. Aurora B is a component of the chromosomal passenger complex (CPC) which includes other proteins such as INCENP survivin and borealin essential for its function.

Biological function summary

Aurora B kinase functions to ensure proper chromosome alignment segregation and cytokinesis during mitosis and meiosis. It phosphorylates various substrates to facilitate processes like correction of kinetochore-microtubule attachments and regulation of the mitotic checkpoint. As a part of the CPC Aurora B acts in coordination with other proteins to control these cellular events ensuring that cells divide accurately and safely.

Pathways

Aurora B integrates into the cell cycle and mitotic pathways operating closely with the spindle assembly checkpoint. It interacts with proteins like CENP-A and CENP-E ensuring error-free chromosome segregation. Aurora B's activity within these pathways is critical for maintaining genomic stability and preventing aneuploidy a condition linked to improper chromosome number.

Associated diseases and disorders

Aurora B's malfunction associates with cancer and chromosomal instability. Overexpression or dysregulation of Aurora B kinase frequently occurs in several types of cancer contributing to tumorigenesis by promoting abnormal cell division. Proteins such as p53 a well-known tumor suppressor often become functionally compromised when Aurora B activity is altered further advancing disease progression. Aurora B also holds implications in other disorders marked by faulty cell cycle regulation emphasizing its potential as a therapeutic target.

    HDACI induced G2/M phase cell cycle and growth inhibition in prostate cancer cells via distinct mechanisms.(A) LBH589 had a dose-dependent effect on growth inhibition in prostate cancer cell lines. The cell lines were treated with 50, 75, 100, and 150 nM of LBH589. Cell survival was measured using MTT assay as described in the Materials and Methods section. Graphs compared the percentage of growth inhibition to vehicle control at 24 (upper) and 48 (lower) hours. (B) LBH589 induced G2/M cell cycle arrest. All cell lines were treated with LBH589 or vehicle control for 24 h. The cell cycles were analyzed by PI-staining and flow cytometry according to DNA content. The increased percentages of G2/M cells were compared to that of vehicle control. (C) LBH589 induced apoptosis in PC-3 and LNCaP cells. Both cell lines were treated with 75nM LBH589 or vehicle control for 24 (upper) and 48 (lower) h. The percentages of apoptotic cells were analyzed by counting the population of DNA fragmentation by flow cytometry. (D–E) HDACIs induced Aurora kinase degradation found in PC-3 but not in LNCaP. PC-3 and LNCaP cells were treated with different HDACIs at indicated concentrations of LBH589, SAHA and SBHA for 24 h and cell lysates were analyzed by western blot using the indicated antibodies. (F) Profile of proteins regarding progression of G2/M cell cycle. The cells were treated with different dosages of LBH589 for 24 h. The lysate was analyzed by western blot.
