E2F1DestructionPathway
E2F-1 is a transcription factor that regulates the expression of genes involved in the cell cycle and that is involved in progression of the cell cycle from G1 into S phase. Over-expression of E2F-1 can induce cellular transformation and its under-expression can repress apoptosis. Association with the tumor suppressor Rb represses E2F-1 activity, and this repression is relieved when the cdk2/cyclin E complex at the G......阅读全文
