  • Function

    Participates 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 specificity

    Expressed in testis, thymus, prostate and ovary and weakly expressed in lung, brain and kidney.
  • Sequence similarities

    Belongs 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 localization

    Cytoplasm. 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.

Functional Studies
Recombinant human GSK3ß (ab60863) was used to phosphorylate putative GSK3ß substrate (protein X). Evidence of phosphorylation was confirmed by:
(1) in-house generated phospho-specific antibody against the putative substrate (Protein X - T236 data shown)
(2) lambda phosphatase treatment of GSK3ß-treated protein X known phospho-specific protein interactor
