Function

[AUKBA_XENLA] 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. Phosphorylates 'Ser-10' of histone H3 during mitosis.^[1] ^[2] ^[3] [INCEA_XENLA] 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. Probably acts through association with aurkb or aurkc. Seems to bind directly to microtubules.^[4] ^[5]

Publication Abstract from PubMed

The members of the Aurora kinase family play critical roles in the regulation of the cell cycle and mitotic spindle assembly and have been intensively investigated as potential targets for a new class of anticancer drugs. We describe a new highly potent and selective class of Aurora kinase inhibitors discovered using a phenotypic cellular screen. Optimized inhibitors display many of the hallmarks of Aurora inhibition including endoreduplication, polyploidy, and loss of cell viability in cancer cells. Structure-activity relationships with respect to kinome-wide selectivity and guided by an Aurora B co-crystal structure resulted in the identification of key selectivity determinants and discovery of a subseries with selectivity toward Aurora A. A direct comparison of biochemical and cellular profiles with respect to published Aurora inhibitors including VX-680, AZD1152, MLN8054, and a pyrimidine-based compound from Genentech demonstrates that compounds 1 and 3 will become valuable additional pharmacological probes of Aurora-dependent functions.
