of the Retinoblastoma gene product (Rb) by CDK4 and/or CDK6 (G1/S checkpoint), leading to the release of bound E2F from Rb and allowing the transcription of genes by “free E2F” necessary for S phase progression. During late G1 phase, CDK2/cyclin E complex phosphorylates

Immunodetection of cyclin D1 and D2/D3 using flow cytometry

that has been kept -20°C. Incubate the cells for at least two hours. Wash once with staining buffer and decant. Add the primary anti-cyclin antibody in a volume of 200 µ l. Incubate overnight at 4°C. Wash twice with cold cyclin staining buffer and add the Cy

E2F Transcription Factors and pRb Pocket Proteins in Cell Cycle Progression

The E2F-family of transcripion factors exerts fascinating and contrasting functions in tran-scriptional repression and activation of genes regulating proliferation, apoptosis, and differentiation. E2F is principally regulated by its temporal
