The M-phase regulatory phosphatase PP2A-B55δ opposes protein kinase A on Arpp19 to initiate meiotic division

The M-phase regulatory phosphatase PP2A-B55δ opposes protein kinase A on Arpp19 to initiate meiotic division

Mechanisms triggering meiotic divisions of oocytes remain unclear. Here, the authors report that meiosis resumption relies on the timely phosphorylation of Arpp19 protein at two distinct sites, which depends on two kinases (PKA and Gwl) and a single phosphatase (PP2A-B55δ).
