  • Function
    Component of the beta-catenin destruction complex required for regulating CTNNB1 levels through phosphorylation and ubiquitination, and modulating Wnt-signaling. Controls dorsoventral patterning via two opposing effects; down-regulates CTNNB1 to inhibit the Wnt signaling pathway and ventralize embryos, but also dorsalizes embryos by activating a Wnt-independent JNK signaling pathway. In Wnt signaling, probably facilitates the phosphorylation of CTNNB1 and APC by GSK3B. Likely to function as a tumor suppressor. Facilitates the phosphorylation of TP53 by HIPK2 upon ultraviolet irradiation. Enhances TGF-beta signaling by recruiting the RNF111 E3 ubiquitin ligase and promoting the degradation of inhibitory SMAD7. Also component of the AXIN1-HIPK2-TP53 complex which controls cell growth, apoptosis and development.
  • Tissue specificity
    Ubiquitously expressed.
  • Involvement in disease
    Hepatocellular carcinoma
    Caudal duplication anomaly
  • Sequence similarities
    Contains 1 DIX domain.
    Contains 1 RGS domain.
  • Domain
    The tankyrase-binding motif (also named TBD) is required for interaction with tankyrase TNKS and TNKS2.
  • Post-translational
    Phosphorylation and dephosphorylation of AXIN1 regulates assembly and function of the beta-catenin complex. Phosphorylated by CK1 and GSK3B. Dephosphorylated by PPP1CA and PPP2CA. Phosphorylation by CK1 enhances binding of GSK3B to AXIN1.
    ADP-ribosylated by tankyrase TNKS and TNKS2. Poly-ADP-ribosylated protein is recognized by RNF146, followed by ubiquitination at 'Lys-48' and subsequent activation of the Wnt signaling pathway.
    Ubiquitinated by RNF146 when poly-ADP-ribosylated, leading to its degradation and subsequent activation of the Wnt signaling pathway. Sumoylation at Lys-857 and Lys-860 prevents ubiquitination and degradation. Sumoylation is required for AXIN1-mediated JNK activation. Deubiquitinated by USP34, deubiquitinated downstream of beta-catenin stabilization step: deubiquitination is important for nuclear accumulation during Wnt signaling to positively regulate beta-catenin (CTNBB1)-mediated transcription.
  • Cellular localization
    Cytoplasm. Nucleus. Membrane. Cell membrane. MACF1 is required for its translocation to cell membrane (By similarity). On UV irradiation, translocates to the nucleus and colocalizes with DAAX (PubMed:17210684).

Thank you so much for your patience! :) As stated on the online datasheet, ab4157 is a "fast track" antibody and thus far, no signal has been obtained but low background was observed in Human Brain, Human Pancreas, MOLT-4 and HeLa lysates at up to 2.0µg/ml. We have had no customer feedback yet regarding this antibody and we greatly appreciate your comments and information about your results. Also, we're awarding $300 Conference Travel Money to the 1st researcher who submits positive or conclusive negative data, more details are located on the online datasheet. I'm currently in contact with the antibody's originator to see if they have any suggestions for you and some more information from you would help us out. What type of samples are you using? At what dilution are you using the primary at? What is your secondary antibody? At approximately what size do you see the band? Thank you, and I look forward to hearing from you.
