Application

Anti-E2F3 polyclonal antibody is used to tag E2F transcription factor 3 proteins for detection and quantitation by Western blotting and in cells and tissues by immunohistochemical (IHC) techniques. It is used as a probe to study the role of E2F transcription factor 3 in the regulation of cell growth, differentiation and cell death and as an oncogene.

Biochem/physiol Actions

E2F3 is a member of the E2F family of transcription factors. The E2F family plays a crucial role in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses. The E2F proteins contain several evolutionally conserved domains found in most members of the family. These domains include a DNA binding domain, a dimerization domain which determines interaction with the differentiation regulated transcription factor proteins (DP), a transactivation domain enriched in acidic amino acids, and a tumor suppressor protein association domain which is embedded within the transactivation domain. This protein and another 2 members, E2F1 and E2F2, have an additional cyclin binding domain. E2F3 binds specifically to retinoblastoma protein pRB in a cell-cycle dependent manner.

General description

E2F transcription factors are key regulators of cell growth, differentiation and cell death. E2F transcription factor 3 (E2F3) can be induced by DNA damage through transcriptional and posttranslational mechanisms wherein it functions as a master regulator of DNA damage response. E2F3, a transcriptional effector that commits cells to enter and progress through S phase, is uniquely amplified in specific human tumours, such as prostate cancer, where its expression is inversely correlated with the survival of patients.
