Protein Information (annotations from UniProt)

Database IDHIV0000560
UniProt IDQ53HL2
Primary gene name(s)CDCA8
Synonym gene name(s)PESCRG3
Protein nameBorealin
Protein functionComponent 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. Major effector of the TTK kinase in the control of attachment-error-correction and chromosome alignment. {ECO:0000269|PubMed:15249581, ECO:0000269|PubMed:15260989, ECO:0000269|PubMed:16571674, ECO:0000269|PubMed:18243099}.
Subcellular locationNucleus, nucleolus {ECO:0000269|PubMed:18946085}. Cytoplasm {ECO:0000269|PubMed:18946085}. Cytoplasm, cytoskeleton, spindle {ECO:0000269|PubMed:15561729}. Chromosome, centromere {ECO:0000269|PubMed:20739936}. 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. Colocalizes with SENP3 in the nucleolus in interphase cells. {ECO:0000269|PubMed:18946085}.
