The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/5000. Predicted molecular weight: 26 kDa.
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).
Post-translational modificationsPhosphorylated 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.
