摘要
Wilms' tumor-1 protein (WT1) is a transcription factor that can either activate or repress genes to regulate cell growth, apoptosis and differentiation. WT1 can act as either a tumor suppressor or an oncogene. The cellular functions of WT1 are predominantly regulated by its various interacting partners. Recently we have found that WT1 can regulate the fidelity of chromosome segregation through its interaction with the spindle assembly checkpoint protein, Mitotic arrest deficient-2 (MAD2). WT1 delays anaphase entry by inhibiting the ubiquitination activity of the Anaphase promoting complex/cyclosome (APC/C). Our findings have revealed an important role of WT1 in the regulation of mitotic checkpoint and genomic stability.
