  • FunctionParticipates in the Wnt signaling pathway. Implicated in the hormonal control of several regulatory proteins including glycogen synthase, MYB and the transcription factor JUN. Phosphorylates JUN at sites proximal to its DNA-binding domain, thereby reducing its affinity for DNA. Phosphorylates MUC1 in breast cancer cells, and decreases the interaction of MUC1 with CTNNB1/beta-catenin. Phosphorylates CTNNB1/beta-catenin. Phosphorylates SNAI1. Plays an important role in ERBB2-dependent stabilization of microtubules at the cell cortex. Prevents the phosphorylation of APC and CLASP2, allowing its association with the cell membrane. In turn, membrane-bound APC allows the localization of MACF1 to the cell membrane, which is required for microtubule capture and stabilization. Phosphorylates MACF1 and this phosphorylation inhibits the binding of MACF1 to microtubules which is critical for its role in bulge stem cell migration and skin wound repair.
  • Tissue specificityExpressed in testis, thymus, prostate and ovary and weakly expressed in lung, brain and kidney.
  • Sequence similaritiesBelongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. GSK-3 subfamily.
    Contains 1 protein kinase domain.
  • Post-translational
    Phosphorylated by AKT1 and ILK1. Activated by phosphorylation at Tyr-216.
  • Cellular localizationCytoplasm. Nucleus. Cell membrane. The phosphorylated form shows localization to cytoplasm and cell membrane. The MEMO1-RHOA-DIAPH1 signaling pathway controls localization of the phosophorylated form to the cell membrane.

Anti-GSK3 beta antibody [Y174] images

  • Predicted band size : 46 kDa

    Lane 1: Wild type HAP1 whole cell lysate (20 µg)
    Lane 2: GSK3B knockout  HAP1 whole cell lysate (20 µg)
    Lanes 1 - 2: Merged signal (red and green). Green - ab32391 observed at 46 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab32391 was shown to recognize GSK3B when GSK3B knockout samples were used, along with additional cross-reactive bands. Wild-type and GSK3B knockout samples were subjected to SDS-PAGE. Ab32391 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 2000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Ab97051 was used as secondary antibody at a dilution of 1/500 and counterstained with hematoxylin.

  • Immunocytochemistry/Immunofluorescence analysis of HeLa cells labelling GSK3 beta with purified ab32391 at 1/500. Cells were fixed with 4% Paraformaldehyde and permeabilised with 0.1% tritonX-100. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG (ab150077) at 1/1000 dilution was used as the secondary antibody. Cells were co-stained with ab7291, a mouse anti-tubulin antibody (1/1000) using ab150120, an Alexa Fluor® 594-conjugated goat anti-mouse IgG (1/1000) as the secondary antibody. Nuclei were counterstained with DAPI (blue).

    For negative control 1, rabbit primary antibody was used followed by anti-mouse secondary antibody (ab150120).
    For negative control 2, mouse primary antibody (ab7291) and anti-rabbit secondary antibody (ab150077) were used.

  • IHC image of GSK3 staining in human breast adenocarcinoma formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab32391, 1/200 diution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

The cells were 4% formaldehyde fixed (10 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.

Thank you for your enquiry. This antibody reacts with both the phosphorylated and non-phosphorylated forms of GSK3 beta. This antibody in fact recognizes the N-terminal region as opposed to the C-terminal region as previously detailed. I have updat...
