| UniProt Protein Function: | AurB: a member of the AUR family of kinases. May be directly involved in regulating the cleavage of polar spindle microtubules and is a key regulator for the onset of cytokinesis during mitosis. Expressed during S and G2/M phase and expression is upregulated in cancer cells during M phase. Localized to the midzone of central spindle in late anaphase and concentrated into the midbody in telophase and cytokinesis. Colocalizes with gamma tubulin in the mid-body. 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. Overexpressed in colorectal and other cancer cell lines and thought to cause aneuploidy via histone phosphorylation. |

| NCBI Summary: | 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] |
