Oocytes are held in meiotic prophase for prolonged periods until hormonal signals trigger meiotic divisions. Key players of M-phase entry are the opposing Cdk1 kinase and PP2AB55δ phosphatase. In Xenopus, the protein Arpp19, phosphorylated at serine 67 by Greatwall, plays an essential role in inhibi...

Dysregulation of Caveolin-1 (CAV1), a key component of caveolae, leads to pleiotropic disorders; yet, the mechanisms controlling its trafficking remain unclear. Here, we show that the lipid droplet (LD) biogenesis factor seipin controls CAV1 localization. Seipin deficiency in mice and HeLa cells ...
