The Proteasome Is Involved in the First Metaphase-to-Anaphase Transition of Meiosis in Rat Oocytes: RESULTS(1)

Localization of the Proteasome in Rat Oocytes During Meiosis Possible changes in proteasome localization during resumption of meiosis were examined by double-staining of spontaneously maturing rat oocytes with antibodies against 20S proteasomes as well as against p-tubulin. We found that in meiotically arrested oocytes the proteasomes are localized at the perinuclear region (Fig. 1, A3)….
