Abstract

We uncovered interlocking mechanisms regulating the temporal proteolysis of the transcriptional repressor E2F8 in cycling cells including SCF Cyclin F in G2, dephosphorylation of Cdk1 sites, and activation of APC/C Cdh1 , but not APC/C Cdc20 during mitotic exit and G1. Differential stabilization under limited APC/C activity allows E2F8 to reaccumulate during late G1 and coregulate S-phase entry.
