| Outline of Final Research Achievements |
In this study, I analyzed the dynamics of the nucleus in the fertilized embryo and in the multinucleated intestinal cell of C. elegans to reveal a diverse mechanisms of the nuclear positioning in the cell. Previously, a motor protein dynein has been known as a major regulator of the nuclear positioning. I found that (1) the sperm-derived nucleus utilizes cytoplasmic streaming that emerges after fertilization to position itself in the proper location in the embryo, and (2) a motor protein kinesin-1 is involved in the nuclear positioning in the intestinal cell. This study will reveal new mechanisms of the nuclear positioning in various cell types.
