Multisite phosphorylation networks as signal processors for Cdk1

Abstract

Selective protein phosphorylation in a time-resolved manner is essential to an ordered progression through the cell cycle. A new study now shows how the phopshoadaptor protein Cks1 acts as a signal processor for Cdk1 by regulating the differential amplification of multiple phosphorylation events to generate a wide range of thresholds during the cell cycle.
