MA5-17070 targets E2F1 in FACS, IHC, pep-ELISA, and WB applications and shows reactivity with Human and Mouse samples.
The MA5-17070 immunogen is purified recombinant fragment of human E2F1 (amino acids: 69-223) expressed in E. Coli.
MA5-17070 detects E2F1 which has a predicted molecular weight of approximately 46.9kDa.
The protein encoded by this gene 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.
