• Product name
    Anti-E2F1 (phospho S364) antibody
    See all E2F1 primary antibodies
  • Description
    Rabbit polyclonal to E2F1 (phospho S364)
  • Host species
  • Specificity
    This antibody is specific for the phosphorylated form of E2F1. Minimal cross-reactivity is seen with non-phosphorylated human E2F1 by peptide ELISA.
  • Tested applications
    Suitable for: IHC-P, WBmore details
  • Species reactivity
    Reacts with: Human
    Does not react with: Mouse
  • Immunogen

    Synthetic peptide: SRMGSpLRAPV-C conjugated to KLH, corresponding to amino acids 360-369 of Human E2F 1.



Our Abpromise guarantee covers the use of ab5391 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration.
WB 1/250. Detects a band of approximately 47 kDa (predicted molecular weight: 47 kDa).


  • Function
    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.
  • Sequence similarities
    Belongs to the E2F/DP family.
  • Post-translational
    Phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase.
    Acetylation stimulates DNA-binding. Enhanced under stress conditions such as DNA damage and inhibited by retinoblastoma protein pRB. Regulated by KAP1/TRIM28 which recruits HDAC1 to E2F1 resulting in deacetylation. Acetylated by P/CAF/KAT2B.

    Lysates were prepared from untreated cells and cells treated with 2µM Doxorubicin used as a DNA damaging agent. The arrow indicates E2F1.

     Phosphorylated E2F1 was only expressed in the treated cells. The blot clearly shows that ab5391 only detected phosphorylated E2F1 in the human cell lines.
