Abstract

Rata et al. combine quantitative assays with mathematical modeling to show that hysteresis of the mitotic switch emerges from mutual effects of Cdk1 and its counteracting phosphatase, PP2A:B55, on each other's auto-activation loops. Their work also reveals an intermediate but hidden steady state between interphase and M phase.
