Technical Data
E2F1, phosphorylated (Ser332) (Transcription Factor E2F1, E2F-1, Retinoblastoma Binding Protein 3, RBBP-3, PRB-binding Protein E2F-1, PBR3, Retinoblastoma-associated Protein 1, RBAP-1, RBBP3)
E2F1 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, E2F2 and E2F3, have an additional cyclin binding domain. This protein binds preferentially to retinoblastoma protein pRB in a cell-cycle dependent manner. It can mediate both cell proliferation and p53-dependent/independent apoptosis.

Suitable for use in ELISA and Dot Blot. Other applications not tested.
