The p53 homolog TAp63α is the transcriptional key regulator of genome integrity in oocytes. After DNA damage, TAp63α is activated by multistep phosphorylation involving multiple phosphorylation events by the kinase CK1, which triggers the transition from a dimeric and inactive conformation to an open and active tetramer that initiates apoptosis ...
