Biochem/physiol Actions

Transcription factor E2F1 is a protein encoded by the E2F1 gene in humans and belongs to E2F family of transcription factors. It is located on chromosome 20q11 and plays a critical role in the transcription of certain genes required for cell cycle progression. E2F1 may facilitate identification of additional E2F family members and detection of E2F1 abnormalities in human tumors. It plays a crutial role in regulating cell cycle and other biological processes in cells. E2F-1 gene expression is higher in rectal cancer tissue compared to normal tissue.
