| Research Abstract |
To elucidate regulatory mechanisms involved in translation and stability of mRNA, it is essential to understand functions of mRNP components. In this work, we further characterized mRNP components RAP55/Lsm14 and P100 that we previously identified. To obtain proteins that functionally interact with RAP55, we performed a screening based on the co-localization with RAP55, effects of the overexpression on the formation of mRNP granules or the disappearance of RAP55 from mRNP granules. In addition, to understand the mechanism with which P100 disappears from oocytes during oocyte maturation, we prepared several point mutants and analyzed their stability.
