| Outline of Final Research Achievements |
Understanding the regulatory mechanism of the cellular potency for differentiation is one of important goals in biological sciences. Based on a recent report by the Gurdon’s group that nuclear F-actin is involved in transcriptional reprogramming induced in the frog oocyte nucleus, we tried to prepare nucleoplasmic extract by the use of frog egg extracts that are able to reproduce intracellular actin dynamics. We have not been successful in its preparation because of technical difficulties but instead have found that in eggs and blastula cells, the early embryonic subtype of an actin-binding protein promotes actin polymerization in the nucleus.
