Progesterone induces meiosis through two obligate co-receptors with PLA2 activity by Nancy Nader, Lama Assaf, Lubna Zarif, Anna Halama, Sharan Yadav, Maya Dib, Nabeel Attarwala, Qiuying Chen, Karsten Suhre, Steven Gross, Khaled Machaca

“…Despite the established physiological importance of P4 nongenomic signaling, the details of its signal transduction cascade remain elusive. Here, using Xenopus oocyte maturation as a well-established physiological readout of nongenomic P4 signaling, we identify the lipid hydrolase ABHD2 (α/β hydrolase domain-containing protein 2) as an essential mPRβ co-receptor to trigger meiosis. …”
