| Outline of Final Research Achievements |
Failure in cell division induces cell death or cell transformation, so that cell division is regulated by various mechanisms. However, it still remain unknown how chromosomes are equally distributed during cell division.
We performed siRNA screening and found that PRMT1, a enzyme that methylates arginine, is essential for cell division. In addition, we found that arginine methylation of UBAP2L was required for equal distribution of chromosomes during cell division. We also found that G3BP and FXR1, which regulate translation, and small nucleolar RNA formed a large RNA-Protein complex with UBAP2L. Our results suggest that arginine methylation of UBAP2L complex may regulates cell division by promoting translation of speicific proteins for cell division.
