E2F-1 has dual roles depending on the cell cycle
The E2F family of transcription factors play a critical role in the control of cell proliferation. E2F-1 is the major cellular target of pRB and is regulated by pRB during cell proliferation. E2F-1-mediated activation and repression of target genes occurs in different settings. The role of E2F-1 and E2F-1/pRB complexes in regulation of different target genes, and in cycling versus quiescent cel...
متن کاملCombinatorial roles for pRB, p107, and p130 in E2F-mediated cell cycle control.
Numerous studies have implicated the pRB family of nuclear proteins in the control of cell cycle progression. Although over-expression experiments have revealed that each of these proteins, pRB, p107, and p130, can induce a G(1) cell cycle arrest, mouse knockouts demonstrated distinct developmental requirements for these proteins, as well as partial functional redundancy between family members....
متن کاملE2F mediates developmental and cell cycle regulation of ORC1 in Drosophila.
Throughout the cell cycle of Saccharomyces cerevisiae, the level of origin recognition complex (ORC) is constant and ORCs are bound constitutively to replication origins. Replication is regulated by the recruitment of additional factors such as CDC6. ORC components are widely conserved, and it generally has been assumed that they are also stable factors bound to origins throughout the cell cycl...
متن کاملRole of E2F in cell cycle control and cancer.
E2F transcription factors regulate the expression of a number of genes important in cell proliferation, particularly those involved in progression through G1 and into the S-phase of the cell cycle. The activity of E2F factors is regulated through association with the retinoblastoma tumor suppressor protein (Rb) and the other pocket proteins, p107 and p130. Binding of Rb, p107 or p130 converts E...
متن کاملCdks, cyclins and CKIs: roles beyond cell cycle regulation.
Cyclin-dependent kinases (Cdks) are serine/threonine kinases and their catalytic activities are modulated by interactions with cyclins and Cdk inhibitors (CKIs). Close cooperation between this trio is necessary for ensuring orderly progression through the cell cycle. In addition to their well-established function in cell cycle control, it is becoming increasingly apparent that mammalian Cdks, c...
