title: Structural principles in cell-cycle control: beyond the CDKs.
abstract: Retinoblastoma protein (Rb) interacts with cyclin-dependent kinases and regulates the transcription of genes necessary for progression through the S phase of the cell cycle. Clues to the atomic mechanisms involved are offered by the structure of the two pocket regions of Rb in complex with a short peptide from a viral oncoprotein. Structures of cyclins, Rb and TFIIB reveal that a common motif occurs in proteins regulating three consecutive events of cell-cycle control.
