Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 26 kDa.
ICC/IF Use a concentration of 10 µg/ml.


  • FunctionMay be involved in calcium-dependent ubiquitination and subsequent proteasomal degradation of target proteins. Probably serves as a molecular bridge in ubiquitin E3 complexes. Participates in the ubiquitin-mediated degradation of beta-catenin (CTNNB1).
  • Sequence similaritiesContains 1 CS domain.
    Contains 1 SGS domain.
  • Post-translational
    Phosphorylated on serine residues. Phosphorylated upon induction by RA or at high calcium concentrations.
  • Cellular localizationNucleus. Cytoplasm. Cytoplasmic at low calcium concentrations. In neuroblastoma cells, after a retinoic acid (RA) induction and calcium increase, it localizes in both the nucleus and cytoplasm. The nuclear fraction may be phosphorylated.
