WitrynaIn oocytes, however, ERK plays a different role; it activates another protein kinase called Rsk, which inhibits action of the anaphase-promoting complex and arrests meiosis at metaphase II (Figure 14.40). Oocytes can remain arrested at this point in the meiotic cell cycle for several days, awaiting fertilization.
