Research Abstract

I found that auto-cleavage of separase, a protease that is inhibited by securin, is crucial for the proper regulation of separase activity, and the timely chromosome segregation. I also showed that a disturbance of the chromosome stability plays a role in the cell transformation induced by over-expression of securin. These data demonstrate the relationship between the function of separase-securin for the stable chromosome segregation and the tumor development.
