Progesterone triggers the first meiotic cell division of Xenopus oocyte and inhibits cAMP synthesis. The effect of pertussis toxin purified from Bordetella pertussis was tested on the maturation of Xenopus oocyte. The toxin did not inhibit progesterone-induced resumption of meiosis or the hormone-induced drop in cAMP level. This indicates that progesterone action is not mediated by the Ni subunit of the oocyte adenylate cyclase. Furthermore, pertussis toxin caused a reduction in the time course of maturation correlated with the precocious appearance of an alkali stable 47 kDa phosphoprotein, a marker of the maturation promoting factor (MPF) activity. Pertussis toxin effects mimicked those of 2-glycerophosphate suggesting that both agents act on the steady-state level of phosphorylation implicated in MPF activity.
