Dual specificity protein phosphatase 7 (DUSP7)

Shows high activity towards MAPK1/ERK2 (PubMed:9788880). Also has lower activity towards MAPK14 and MAPK8 (PubMed:9788880).

In arrested oocytes, plays a role in meiotic resumption (By similarity). Promotes nuclear envelope breakdown and activation of the CDK1/Cyclin-B complicated in oocytes, likely by dephosphorylating and inactivating the conventional protein kinase C (cPKC) isozyme PRKCB (By similarity).
