      The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

      One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

    Target

    • Function

      Multifunctional nucleolar protein that terminates ribosomal gene transcription, mediates replication fork arrest and regulates RNA polymerase I transcription on chromatin. Plays a dual role in rDNA regulation, being involved in both activation and silencing of rDNA transcription. Interaction with BAZ2A/TIP5 recovers DNA-binding activity.
    • Sequence similarities

      Contains 2 Myb-like domains.
    • Domain

      The N-terminal region (NRD) inhibits DNA-binding via its interaction with the C-terminal region.
    • Post-translational
      modifications

      Phosphorylated upon DNA damage, probably by ATM or ATR.
    • Cellular localization

      Nucleus. Nucleus > nucleolus.

      Question

      I would like to know if your TTF-1 Abs are against Transcription
      Termination Factor 1 or Thyroid transcription factor that is encoded by
      the NKX2-1 gene, tehre seems to be a bit of confusion on the Abcam
      reference sheets .

      Asked on Mar 20 2012

      Answer

      Thank you for keeping in touch.

      Please take my apologies for the long delay of my reply. I have contacted the originators of some of our relevant antibodies in order to get a confirmation (mistakes can happen, especially with those similar target names).

      Now I am happy to let you know that all of our TTF1 antibodies are directed against theThyroid transcription factor 1, also known as NKX2-1(SwissProtID P43699, http://www.uniprot.org/uniprot/P43699), as also stated in the Alternative names section on each datasheet.

      The antibodies in our catalogue that recognise the Transcription Termination Factor 1 (SwissProtID Q15361, http://www.uniprot.org/uniprot/Q15361) can be found under this full name, as for example ab87726 (https://www.abcam.com/TTF1-antibody-ab87726.html (or use the following: https://www.abcam.com/TTF1-antibody-ab87726.html).).

      Thank you again for checking with us and for your patience.

      I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
