Synonyms
  1. SUMO1-protein E3 ligase Topors
  2. Topoisomerase I-binding RING finger protein
  3. Topoisomerase I-binding arginine/serine-rich protein
  4. Tumor suppressor p53-binding protein 3

Gene Name TOPORS
Protein Type Enzyme
Biological Properties
General Function Involved in protein binding
Specific Function Functions as an E3 ubiquitin-protein ligase and as an E3 SUMO1-protein ligase. Probable tumor suppressor involved in cell growth, cell proliferation and apoptosis that regulates TP53 stability through ubiquitin-dependent degradation. May regulate chromatin modification through sumoylation of several chromatin modification-associated proteins. May be involved in DNA damage- induced cell death through IKBKE sumoylation
