CACYBP a nuclear/cytoplasmic protein involved in calcium-dependent ubiquitination and proteosomal degradation of target proteins. A possible molecular bridge in ubiquitin E3 complexes. Participates in the ubiquitin-mediated degradation of beta-catenin (CTNNB1). Interacts with proteins of the S100 family at physiological calcium concentrations. Component of some large E3 complexes and interacts directly with SIAH1, SIAH2 and SKP1A. 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. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
