Abstract:
The CPC [chromosomal passenger complex; INCENP (inner centromere protein), Aurora B kinase, survivin and borealin] is implicated in many mitotic processes. In the present paper we describe how we generated DT40 conditional-knockout cell lines for incenp1 and survivin1 to better understand the role of these CPC subunits in the control of Aurora B kinase activity. These lines enabled us to reassess current knowledge of survivin function and to show that INCENP acts as a rheostat for Aurora B activity.
