CC -!- FUNCTION: Serine/threonine-protein kinase component of the chromosomal
CC passenger complex (CPC), a complex that acts as a key regulator of
CC mitosis (By similarity). The CPC complex has essential functions at the
CC centromere in ensuring correct chromosome alignment and segregation and
CC is required for chromatin-induced microtubule stabilization and spindle
CC assembly (By similarity). Involved in the bipolar attachment of spindle
CC microtubules to kinetochores and is a key regulator for the onset of
CC cytokinesis during mitosis (PubMed:9450992). Required for
CC central/midzone spindle assembly and cleavage furrow formation (By
CC similarity). Key component of the cytokinesis checkpoint, a process
CC required to delay abscission to prevent both premature resolution of
CC intercellular chromosome bridges and accumulation of DNA damage:
CC phosphorylates CHMP4C, leading to retain abscission-competent VPS4
CC (VPS4A and/or VPS4B) at the midbody ring until abscission checkpoint
CC signaling is terminated at late cytokinesis (By similarity). AURKB
CC phosphorylates the CPC complex subunits BIRC5/survivin, CDCA8/borealin
CC and INCENP (By similarity). Phosphorylation of INCENP leads to
CC increased AURKB activity (By similarity). Other known AURKB substrates
CC involved in centromeric functions and mitosis are CENPA, DES/desmin,
CC GPAF, KIF2C, NSUN2, RACGAP1, SEPTIN1, VIM/vimentin, HASPIN, and histone
CC H3 (By similarity). A positive feedback loop involving HASPIN and AURKB
CC contributes to localization of CPC to centromeres (By similarity).
CC Phosphorylation of VIM controls vimentin filament segregation in
CC cytokinetic process, whereas histone H3 is phosphorylated at 'Ser-10'
CC and 'Ser-28' during mitosis (H3S10ph and H3S28ph, respectively) (By
CC similarity). A positive feedback between HASPIN and AURKB contributes
CC to CPC localization (By similarity). AURKB is also required for
CC kinetochore localization of BUB1 and SGO1 (By similarity).
CC Phosphorylation of p53/TP53 negatively regulates its transcriptional
CC activity (By similarity). Key regulator of active promoters in resting
CC B- and T-lymphocytes: acts by mediating phosphorylation of H3S28ph at
CC active promoters in resting B-cells, inhibiting RNF2/RING1B-mediated
CC ubiquitination of histone H2A and enhancing binding and activity of the
CC USP16 deubiquitinase at transcribed genes (By similarity). Acts as an
CC inhibitor of CGAS during mitosis: catalyzes phosphorylation of the N-
CC terminus of CGAS during the G2-M transition, blocking CGAS liquid phase
CC separation and activation, and thereby preventing CGAS-induced
CC autoimmunity (By similarity). Phosphorylates KRT5 during anaphase and
CC telophase (By similarity). {ECO:0000250|UniProtKB:O70126,

CC EC=2.7.11.1; Evidence={ECO:0000250|UniProtKB:Q96GD4};
CC -!- ACTIVITY REGULATION: Activity is greatly increased when AURKB is within
CC the CPC complex. In particular, AURKB-phosphorylated INCENP acts as an
CC activator of AURKB. Positive feedback between HASPIN and AURKB
CC contributes to CPC localization. {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- SUBUNIT: Component of the chromosomal passenger complex (CPC) composed
CC of at least BIRC5/survivin, CDCA8/borealin, INCENP, AURKB or AURKC;
CC predominantly independent AURKB- and AURKC-containing complexes exist.
CC Associates with RACGAP1 during M phase. Interacts with CDCA1, EVI5,
CC JTB, NDC80, PSMA3, SEPTIN1, SIRT2 and TACC1. Interacts with SPDYC; this
CC interaction may be required for proper localization of active, Thr-235-
CC phosphorylated AURKB form during prometaphase and metaphase. Interacts
CC with p53/TP53. Interacts (via the middle kinase domain) with NOC2L (via
CC the N- and C-terminus domains). Interacts with TTC28 (By similarity).
CC Interacts with RNF2/RING1B (By similarity).

CC {ECO:0000250|UniProtKB:Q96GD4}. Chromosome, centromere, kinetochore

CC {ECO:0000250|UniProtKB:Q96GD4}. Midbody {ECO:0000250|UniProtKB:Q96GD4}.
CC Note=Localizes on chromosome arms and inner centromeres from prophase
CC through metaphase and then transferring to the spindle midzone and
CC midbody from anaphase through cytokinesis. Colocalized with gamma
CC tubulin in the midbody. Proper localization of the active, Thr-235-
CC phosphorylated form during metaphase may be dependent upon interaction
CC with SPDYC. Colocalized with SIRT2 during cytokinesis with the midbody.
CC Localization (and probably targeting of the CPC) to the inner
CC centromere occurs predominantly in regions with overlapping mitosis-
CC specific histone phosphorylations H3pT3 and H2ApT12.
CC {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- TISSUE SPECIFICITY: High level expression seen in the testis. It is
CC also expressed in the spleen, lung and heart. Expressed in the G2/M
CC phase of the cell cycle. {ECO:0000269|PubMed:9450992}.
CC -!- PTM: The phosphorylation of Thr-235 requires the binding to INCENP and
CC occurs by means of an autophosphorylation mechanism. Thr-235
CC phosphorylation is indispensable for the AURKB kinase activity.
CC {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- PTM: Acetylated at Lys-218 by KAT5 at kinetochores, increasing AURKB
CC activity and promoting accurate chromosome segregation in mitosis.
CC {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- PTM: Ubiquitinated by different BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase
CC complexes. Ubiquitinated by the BCR(KLHL9-KLHL13) E3 ubiquitin ligase
CC complex, ubiquitination leads to removal from mitotic chromosomes and
CC is required for cytokinesis. During anaphase, the BCR(KLHL21) E3
CC ubiquitin ligase complex recruits the CPC complex from chromosomes to
CC the spindle midzone and mediates the ubiquitination of AURKB.
CC Ubiquitination of AURKB by BCR(KLHL21) E3 ubiquitin ligase complex may
CC not lead to its degradation by the proteasome.
CC {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. Aurora subfamily. {ECO:0000255|PROSITE-
CC ProRule:PRU00159}.
