HowProgesteroneInitiatesOocyteMembrane
Progesterone (Pg) binds to both intracellular iPR and plasma membrane- bound mPR. (Right Top) After binding to Pg, iPR is recruited to the membrane associated protein tyrosine kinase p60c- src, which induces activation of the MAPK signaling pathway. This results in activation of p90Rsk and the subsequent phosphorylation and inactivation of Myt1, which favors formation of the activated cell cycle complex cyclin B-Cdc2......阅读全文
