Microinjection of pp60v-src into Xenopus oocytes increases phosphorylation of ribosomal protein S6 and accelerates the rate of progesterone-induced meiotic maturation

Mol Cell Biol. 1984 Aug;4(8):1631-4. doi: 10.1128/mcb.4.8.1631-1634.1984.

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.
