In vertebrates, unfertilized eggs are arrested at metaphase of meiosis II by Emi2, a direct inhibitor of the APC/C ubiquitin ligase. Two different ubiquitin-conjugating enzymes, UbcH10 and Ube2S, work ...
This is a preview. Log in through your library . Abstract During interkinesis, a metaphase II (Metll) spindle is built immediately after the completion of meiosis I. Oocytes then remain Metll arrested ...
Mitotic divisions result from the oscillating activity of cyclin-dependent kinase 1 (Cdk1). Cdk1 activity is terminated by the anaphase-promoting complex/cyclosome (APC/C), a ubiquitin ligase that ...
