General annotation (Comments)

Function	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. In the complex, it may be required to direct the CPC to centromeric DNA. Ref.6 Ref.7 Ref.13
Subunit structure	May form homooligomers. Component of the CPC at least composed of BIRC5/survivin, CDCA8/borealin, INCENP and AURKB/Aurora-B.
Subcellular location	Nucleus › nucleolus. Cytoplasm. Centromere. 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. Ref.7 Ref.8 Ref.10 Ref.12 Ref.14
Developmental stage	Cell-cycle regulated. Increases during G2/M phase and then reduces after exit from M phase. Ref.10
Miscellaneous	Cells lacking CDCA8 display a slight decrease in histone H3 'Ser-10' phosphorylation, suggesting that the CPC complex mediates phosphorylation of 'Ser-10' of histone H3.
Sequence similarities	Belongs to the borealin family.
Sequence caution	The sequence BG354581 differs from that shown. Reason: Frameshift at positions 123 and 200.
