Description | ChIPAb+ E2F-1 - ChIP Validated Antibody and Primer Set |
Overview | All ChIPAb+ antibodies are individually validated for chromatin precipitation, every lot, every time. Each ChIPAb+ antibody set includes control primers (tested every lot by qPCR) to biologically validate your IP results in a locus-specific context. The qPCR protocol and primer sequences are provided, allowing researchers to validate ChIP protocols when using our antibody in their chromatin context. Each set also includes a negative control antibody to ensure specificity of the ChIP reaction. The ChIPAb+ E2F-1 set includes the E2F-1 antibody, a negative control normal mouse IgG, and qPCR primers which amplify a 100 bp region of human CDC2 promoter. The E2F-1 and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of E2F-1-associated chromatin. |

Background Information | E2F-1 was identified as a cellular protein with DNA binding activity associated with the adenovirus E2 gene promoter. The original member of the E2F family of transcription factors, now consisting of five, was identified through its association with the retinoblastoma protein, which controls its activity. E2F-1 is cell cycle regulated with very low levels in early G1 then increasing levels as cells move from G1 to S with highest levels of protein at the G1/S boundary, which is consistent with its role in S-phase entry. |

Application Notes | Chromatin Immunoprecipitation: Representative lot data. Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 1 µL of either Normal Mouse IgG or 1 µL of Anti-E2F-1 and the Magna ChIP™ G Kit (Cat. # 17-611). Successful immunoprecipitation of E2F-1-associated DNA fragments was verified by qPCR using ChIP Primers, human CDC2 promoter as a positive locus, and an intergenic region near human CALML5 as a negative locus. (Please see figures). Data is presented as percent input of each IP sample relative to input chromatin for each amplicon and ChIP sample as indicated. Please refer to the EZ-Magna ChIP™ G (Cat. # 17-409) or EZ-ChIP™ (Cat. # 17-371) protocol for experimental details. Western Blot Analysis: Representative lot data. HeLa nuclear extract was resolved by electrophoresis, transferred to PVDF and probed with Anti-E2F-1 (1.0 µg/mL). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemiluminescence detection system. Arrow indicates E2F-1 (~55 kDa) (Please see figures). Immunoprecipitation: 4 μg of a previous lot of this antibody immunoprecipitated E2F-1 from HeLa nuclear extract. Electrophoretic Mobility Shift Assay (EMSA): A previous lot of the antibody has been shown to gel shift the E2F-1/DP-1/DNA complex. |

Entrez Gene Number |
|
Entrez Gene Summary | 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. |

UniProt Summary | FUNCTION: SwissProt: Q01094 # Transcription activator that binds DNA cooperatively with dp proteins through the E2 recognition site, 5-TTTC[CG]CGC- 3 found in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication. The DRTF1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. E2F-1 binds preferentially RB1 protein, in a cell-cycle dependent manner. It can mediate both cell proliferation and p53-dependent apoptosis. SIZE: 437 amino acids; 46920 Da SUBUNIT: Component of the DRTF1/E2F transcription factor complex. Forms heterodimers with DP family members. 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. Viral oncoproteins, notably E1A, T- antigen and HPV E7, are capable of sequestering RB protein, thus releasing the active complex. Interacts with TRRAP, which probably mediates its interaction with histone acetyltransferase complexes, leading to transcription activation. Binds TOPBP1 and EAPP. Interacts with ARID3A. SUBCELLULAR LOCATION: Nucleus. PTM: Phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase. SIMILARITY: SwissProt: Q01094 ## Belongs to the E2F/DP family. |
