Function
Female meiosis-specific activator of the anaphase promoting complex/cyclosome (APC/C) (PubMed:17251266, PubMed:18020708). Required for the completion of meiosis in oocytes (PubMed:11252055, PubMed:10683177, PubMed:10924478, PubMed:17251266, PubMed:18020708). Activates the ubiquitin ligase activity and substrate specificity of APC/C and triggers the sequential degradation of mitotic cyclins in meiosis (PubMed:17251266, PubMed:18020708). Promotes the ubiquitination and degradation of CycA early in meiosis I and the degradation of CycB and CycB3 after egg activation (PubMed:18020708). Promotes degradation of mtrm at the oocyte-to-embryo transition (PubMed:24019759).
