Microtubule protein synthesis during oogenesis and early embryogenesis in Xenopus laevis.

???displayArticle.abstract???
A method is described which permits the preparation of descrete classes of oocytes of different sizes from all stages of oogenesis in Xenopus laevis. This technique is used in the determination of the content of microtubule protein in oocytes during the course of oogenesis. These experiments show that microtubule protein is present in oocytes of all sizes assayed and that the amount is simply related to the volume of the oocyte. In the largest oocytes microtubule protein constitutes 1% of the soluble protein and this amount does not change on maturation and fertilization. These results show that the changes occurring in the oocyte on maturation which allow the cytoplasm to support microtubule polymerization occur as a result of a modification of the pre-existing microtubule protein, not from protein synthesis de novo. These experiments also indicate that the synthesis of microtubule protein either form 'masked' mRNA or from newly synthesized mRNA plays an insignificant role in microtubule protein synthesis at maturation, ovulation and immediately post-fertilization.
