ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.



  • Function
    May 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 similarities
    Contains 1 CS domain.
    Contains 1 SGS domain.
  • Post-translational
    Phosphorylated on serine residues. Phosphorylated upon induction by RA or at high calcium concentrations.
  • Cellular localization
    Nucleus. 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.
