Summary: APC/CCdh1 ubiquitylates both borealin, via a non-canonical degron motif, and Aurora B to terminate activity of the CPC in G1 phase. Disruption of this ubiquitylation reduces the efficiency of DNA replication.

The chromosomal passenger complex (CPC) is a key regulator of cell division. Its proper localization during the different phases of mitosis and cytokinesis is crucial for the exertion of its various functions. HDACi treatment has been demonstrated to disturb the centromeric localization of the CPC in tumor cells, thus leading to severe mitotic defe...

Borealin, a member of the chromosomal passenger complex, plays a key regulatory role at centromeres and the central spindle during mitosis. Loss of Borealin leads to defective cell proliferation and early embryonic lethality. The in vivo functions of Borealin in mammalian postnatal development, tissue homeostasis, and tumorigenesis remain elusive. ...
Borealin/Dasra B, also called cell division cycle associated 8, is a member of the chromosomal passenger complex and plays a crucial role during mitosis and cell division. The expression of this gene has been investigated in several kinds of cancers, but its role in colorectal cancers (CRC) remains to be elucidated. In this study, our in silico ana...

BackgroundSurvivin is a protein that is normally present only in G2 and M-phases in somatic cells, however, in cancer cells, it is expressed throughout the cell cycle. A prosurvival factor, survivin is both an inhibitor of apoptosis and an essential mitotic protein, thus it has attracted much attention as a target for new oncotherapies. Despite its...
Cytokinesis controls the proper segregation of nuclear and cytoplasmic materials at the end of cell division. The chromosomal passenger complex (CPC) has been proposed to monitor the final separation of the two daughter cells at the end of cytokinesis in order to prevent cell abscission in the presence of DNA at the cleavage site, but the precise m...

Maintaining undifferentiated state and self-renewal ability of embryonic stem cells is a process that many genes and factors participate in. Using bioinformatics analyses and suppression subtractive hybridization we cloned a novel human gene related to the proliferation of human embryonic stem (hES) cells and its mouse homologue and identified them...
