Application Abreviews Notes
ICC/IF Use a concentration of 1 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 36 kDa (predicted molecular weight: 36 kDa).


  • Function
    Acts as a transcriptional coactivator of ATF2.
  • Domain
    The leucine-zipper domain is required for coactivation activity. When this domain is deleted, the protein is able to stimulate transcription from a number of gene promoters.
  • Post-translational
  • Cellular localization
  • Information by UniProt
  • Database links
  • Form
    UTF1 is a transcriptional coactivator expressed in pluripotent embryonic stem cells and extra-embryonic cells. Upon activation by Oct-3/4, UTF1 may be responsible for the rapid proliferation and tumorigenic properties of embryonic stem cells. Sox2 is also part of the Oct-3/4-containing complex able to bind the regulatory region of UTF1. UTF1 acts as a transcriptional coactivator of ATF2 and it binds to the N-terminal region of ATF2. Associates with the TFIID complex through interaction with TBP.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 36 kDa
    Observed band size: 46 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 36 kDa, 85 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 30 seconds

    The expression profile observed is consistent with what has been described in the literature (PMID:17785516).
  • ICC/IF image of ab105090 stained mouse embryonic stem cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab105090, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% formaldehyde fixed (10 min) mouse ES cells at 1µg/ml.
