Immunohistochemistry (IHC)

(Anti-E2F1 antibody IHC of human breast carcinoma. Immunohistochemistry of formalin-fixed, paraffin-embedded tissue after heat-induced antigen retrieval. Antibody concentration 10 ug/ml.)

Western Blot (WB)

(Western blot of Affinity Purified anti-E2F-1 pS364 antibody shows detection of a band at ~47 kD corresponding to phosphorylated E2F-1 in induced cell lysates. Panel A shows reactivity using a control antibody reactive to all forms of E2F (arrowheads). Panel B shows specific reactivity against phosphorylated E2F-1 (arrowheads) using our anti-E2F-1 pS364 antibody. Lysates are as follows: CRE/E2F-1 are CRE cells derived from mouse NIH3T3 line transfected with human E2F-1, NIH-3T3 used as a negative control, and MDA-MB-231 cells are a human breast cancer line. As indicated each lysate was prepared from untreated cells and cells treated with 2 uM Doxorubicin used as a DNA damaging agent. In addition the MDA-MB-231 cells were also treated with genistein, a mild DNA damaging agent. The figure shows the same membrane first probed with the anti-E2F-1 pS364 antibody used at a 1:250 dilution, then stripped and re-probed with the pan E2F antibody used as a positive control. The positive control antibody clearly shows an E2F-1 band in all human cell lines, but not mouse cells. Treatment with doxorubicin increases expression of E2F-1 as shown in Panel A. Images were overlapped to confirm that anti-E2F-1 pS364 staining shown treated human cells in Panel B specifically aligns with E2F-1 staining shown in Panel A. Blots can be processed with HRP conjugated Gt-a-Rabbit IgG MX10 for 45 min at room temperature for ECL detection. Personal Communication, XiaoHe Yang, Univ. Oklahoma.)

E2F-1 (also known as transcription factor E2F-1, Retinoblastoma binding protein 3, RBBP-3, PRB-binding protein E2F-1, PBR3, Retinoblastoma-associated protein 1 and RBAP-1) is a transcription activator that binds DNA cooperatively with DP proteins through the E2 recognition site, 5'-TTTC[CG]CGC-3'. 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.

NCBI Description

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. [provided by RefSeq, Jul 2008]

Uniprot Description

E2F1: a member of the E2F/DP 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. Binds DNA cooperatively with Dp transcription factors in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication.The Dp-1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. The E2F-1 complex binds specifically hypophosphorylated retinoblastoma protein RB1. During the cell cycle, RB1 becomes phosphorylated in mid-to-late G1 phase, detaches from the DRTF1/E2F complex, rendering E2F transcriptionally active. Phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase. It can mediate both cell proliferation and p53-dependent apoptosis.
