Human Gene AURKB (ENST00000316199.10) Description and Page Index
  Description: Homo sapiens aurora kinase B (AURKB), transcript variant 10, non-coding RNA. (from RefSeq NR_132730)
RefSeq Summary (NM_001284526): This gene encodes a member of the aurora kinase subfamily of serine/threonine kinases. The genes encoding the other two members of this subfamily are located on chromosomes 19 and 20. These kinases participate in the regulation of alignment and segregation of chromosomes during mitosis and meiosis through association with microtubules. A pseudogene of this gene is located on chromosome 8. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2015].

DESCRIPTION: RecName: Full=Aurora kinase B; EC=2.7.11.1; AltName: Full=Aurora 1; AltName: Full=Aurora- and IPL1-like midbody-associated protein 1; Short=AIM-1; AltName: Full=Aurora/IPL1-related kinase 2; Short=ARK-2; Short=Aurora-related kinase 2; AltName: Full=STK-1; AltName: Full=Serine/threonine-protein kinase 12; AltName: Full=Serine/threonine-protein kinase 5; AltName: Full=Serine/threonine-protein kinase aurora-B;
FUNCTION: Serine/threonine-protein kinase component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. 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. Involved in the bipolar attachment of spindle microtubules to kinetochores and is a key regulator for the onset of cytokinesis during mitosis. Required for central/midzone spindle assembly and cleavage furrow formation. AURKB phosphorylates the CPC complex subunits BIRC5/survivin, CDCA8/borealin and INCENP. Phosphorylation of INCENP leads to increased AURKB activity. Other known AURKB substrates involved in centromeric functions and mitosis are CENPA, DES/desmin, GPAF, KIF2C, NSUN2, RACGAP1, SEPT1, VIM/vimentin, GSG2/Haspin, and histone H3. A positive feedback loop involving GSG2 and AURKB contributes to localization of CPC to centromeres. Phosphorylation of VIM controls vimentin filament segregation in cytokinetic process, whereas histone H3 is phosphorylated at 'Ser-10' and 'Ser-28' during mitosis. A positive feedback between GSG2 and AURKB contributes to CPC localization. AURKB is also required for kinetochore localization of BUB1 and SGOL1. Phosphorylation of p53/TP53 negatively regulates its transcriptional activity.
CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein.
COFACTOR: Magnesium.
ENZYME REGULATION: Activity is greatly increased when AURKB is within the CPC complex. In particular, AURKB-phosphorylated INCENP acts as an activator of AURKB. Positive feedback between GSG2 and AURKB contributes to CPC localization.
SUBUNIT: Component of the chromosomal passenger complex (CPC) composed of at least BIRC5/survivin, CDCA8/borealin, INCENP, AURKB and AURKC. Associates with RACGAP1 during M phase. Interacts with CDCA1, EVI5, JTB, NDC80, PSMA3, SEPT1 and TACC1. Interacts with SPDYC; this interaction may be required for proper localization of active, Thr-232-phosphorylated AURKB form during prometaphase and metaphase. Interacts with p53/TP53. Interacts (via the middle kinase domain) with NOC2L (via the N- and C-terminus domains).
INTERACTION: O15392:BIRC5; NbExp=2; IntAct=EBI-624291, EBI-518823; O15392-1:BIRC5; NbExp=2; IntAct=EBI-624291, EBI-518838; O15392-2:BIRC5; NbExp=2; IntAct=EBI-624291, EBI-518842; Q9NQS7:INCENP; NbExp=3; IntAct=EBI-624291, EBI-307907; Q8WYJ6:SEPT1; NbExp=6; IntAct=EBI-624291, EBI-693002; O75410-6:TACC1; NbExp=2; IntAct=EBI-624291, EBI-624278;
SUBCELLULAR LOCATION: Nucleus. Chromosome. Chromosome, centromere. Cytoplasm, cytoskeleton, spindle. Note=Localizes on chromosome arms and inner centromeres from prophase through metaphase and then transferring to the spindle midzone and midbody from anaphase through cytokinesis. Colocalized with gamma tubulin in the mid- body. Proper localization of the active, Thr-232-phosphorylated form during metaphase may be dependent upon interaction with SPDYC.
TISSUE SPECIFICITY: High level expression seen in the thymus. It is also expressed in the spleen, lung, testis, colon, placenta and fetal liver. Expressed during S and G2/M phase and expression is up-regulated in cancer cells during M phase.
INDUCTION: Expression is cell cycle-regulated, with a low in G1/S, an increase during G2 and M. Expression decreases again after M phase.
PTM: The phosphorylation of Thr-232 requires the binding to INCENP and occurs by means of an autophosphorylation mechanism. Thr-232 phosphorylation is indispensable for the AURKB kinase activity.
PTM: Ubiquitinated by different BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase complexes. Ubiquitinated by the BCR(KLHL9-KLHL13) E3 ubiquitin ligase complex, ubiquitination leads to removal from mitotic chromosomes and is required for cytokinesis. During anaphase, the BCR(KLHL21) E3 ubiquitin ligase complex recruits the CPC complex from chromosomes to the spindle midzone and mediates the ubiquitination of AURKB. Ubiquitination of AURKB by BCR(KLHL21) E3 ubiquitin ligase complex may not lead to its degradation by the proteasome.
DISEASE: Note=Disruptive regulation of expression is a possibile mechanism of the perturbation of chromosomal integrity in cancer cells through its dominant-negative effect on cytokinesis.
SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Aurora subfamily.
SIMILARITY: Contains 1 protein kinase domain.
SEQUENCE CAUTION: Sequence=AAH13300.2; Type=Erroneous initiation; Note=Translation N-terminally shortened;

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
