title: Microinjection of pp60v-src into Xenopus oocytes increases phosphorylation of ribosomal protein S6 and accelerates the rate of progesterone-induced meiotic maturation.
abstract: Microinjection of purified pp60v-src into Xenopus oocytes caused the phosphorylation of ribosomal protein S6 on serine residues and also increased total protein phosphorylation, with almost a two-fold increase in the percentage of phosphotyrosine present. In addition, pp60v-src accelerated the time course of progesterone-induced oocyte maturation, suggesting that the biochemical pathway influenced by pp60v-src is related to that induced by progesterone.
