Abstract
The c-mos proto-oncogene product, pp39mos, is present in unfertilized Xenopus eggs, and disappears on fertilization. Microinjection of synthetic mos RNA into two-cell embryos induces cleavage arrest at metaphase. By contrast, egg cytosol extracts, when immunodepleted of endogenous pp39mos, lose their cleavage-arresting activity in injected embryos. These results demonstrate that Mos protein is the cytostatic factor CSF, long known as an endogenous meiotic inhibitor in vertebrate eggs.Entities:
