The accurate transition from G1 phase of the cell cycle to S phase is crucial for the control of eukaryotic cell proliferation, and its misregulation promotes oncogenesis. During G1 phase, growth-dependent cyclin-dependent kinase (CDK) activity promotes DNA replication and initiates G1-to-S ...
Fig. 1.Regulation of the G1/S transition by the Cdk4/6–cyclin D/INK4/Rb pathway. Progression through the G1 phase of the cell cycle is controlled by the functional state of the Rb family of proteins, pRb, p107 and p130. In G0, Rb proteins are non-phosphorylated, a state that ...
G1 refers to the first gap of time in the cell cycle and G2 refers to gap number two. The other phases of the cell cycle, S and M, refer to the terms "synthesis" and "mitosis," respectively. Within the G1 phase, the subphases ...

Cyclin-dependent kinases (CDKs) activate the firing of replication origins during the S phase of the cell cycle. They also block re-initiation of DNA replication within a single cell cycle, by preventing the assembly of prereplicative complexes at origins. We show here that, in budding yeast,...
The retinoblastoma protein (Rb) has traditionally been associated with regulating the progression of cells through the G1 restriction checkpoint of the cell cycle. There is increasing evidence that Rb is also involved in controlling the progression of cells through S phase. We have evidence that Rb...

During G1 phase of the cell cycle, Rb binds to E2F-DP1 and inhibits downstream transcription. When it is time for a cell to enter S phase, the inactivating phosphorylation of Rb by the G1/S CDKs results in the release of Rb from E2F-DP1 and allows for the activation of E2F target ...
