Target

  • Function

    Transcription factor that binds to GC box promoter elements. Activates the transcription of these genes.

  • Tissue specificity

    Expressed only in testis and placenta.

  • Sequence similarities

    Belongs to the krueppel C2H2-type zinc-finger protein family.
    Contains 3 C2H2-type zinc fingers.

  • Post-translational
    modifications

    Ubiquitinated. Polyubiquitination involves WWP1 and leads to proteasomal degradation of this protein.

  • Cellular localization

    Nucleus.
  • Information by UniProt

  • Database links

    • Form

      KLF5 (also known as basic transcription element-binding protein 2, BTEB2, and intestine enriched krüppel-like factor, IKLF), appears to play a central role in the regulation of intestinal epithelial renewal in both the small intestine and colon. KLF5 also regulates adipocyte differentiation.

    Question

    We did indeed purchase this antibody for use in mouse samples and after extensive testing and use, were unable to detect any reactivity in lung issue. We now know why this occurred. You might also want to reevaluate the RFP antibody for use in mice, ab62341. We had invested considerable time and resources investigating these antibodies and wish to receive compensation.

    We currently use several antibodies from Abcam.
    We would like ab51317 and ab13970 to be sent to us.

    Answer

    Thank you for your reply.

    I'd be happy to replace ab24331. Which of the 2 antibodies (ab51317 and ab13970) would you like me to send?

    As for ab62341 (which is not affected by the product information sent out for ab24331), we would require additionalinformation about the experiment, such as:

    1) What application was used?
    2) What was the sample type? How was it prepared?
    3) What was the exact problem?
    4) Whichantibody dilutions/incubation times were used?
    5) What was used as detection system and as blocking reagent?
    6) What is your orderor PO number for ab62341?
    This antibody is covered under our Abpromise guarantee for 6 months after purchase if used in the tested applications as listed on the datasheet.

    I look forward to hear back from you and assist you further.
