Regulation of Myt1 kinase activity via its N-terminal region in Xenopus meiosis and mitosis
{{output}}
Immature animal oocytes are naturally arrested at the first meiotic prophase (Pro-I), which corresponds to the G2 phase of the cell cycle. In Xenopus oocytes, Myt1 kinase phosphorylates and inactivates cyclin-dependent kinase 1 (Cdk1) at Pro-I, thereby prevent... ...
