孕酮处理后，非洲爪蟾卵母细胞成熟过程中，在生殖囊泡破裂时，一种活性促成熟因子的形成和蛋白质磷酸化的强烈爆发同时发生。在这里，我们表明，这种磷酸化的网站之一是40-S核糖体蛋白S6。这一观察结果进行了讨论，在G2-M过渡期间的体细胞中的成熟促进因子的已知存在和S6磷酸化的增加，观察到在细胞中与促有丝分裂刺激处理。
The formation of an active maturation-promoting factor and a strong burst of protein phosphorylation occur together at germinal vesicle breakdown in Xenopus oocytes undergoing maturation after progesterone Treatment. Here we show that one of the sites of this phosphorylation is the 40-S ribosomal protein S6. This observation is discussed in relation to the known presence of a maturation promoting factor in somatic cells during the G2-M transition and to the increase in S6 phosphorylation observed in cells treated with mitogenic stimuli.
