General annotation (Comments)
| Function | E3 ubiquitin ligase catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins. These substrates include FILIP1, p53/TP53, CDKN1A and TERT. Keeps cells alive by suppressing p53/TP53 under normal conditions, but stimulates apoptosis by repressing CDKN1A under stress conditions. Acts as a negative regulator of telomerase. Has negative and positive effects on RNA polymerase II-dependent transcription. Ref.12 Ref.14 |
| Pathway | |
| Subunit structure | Interacts with p53/TP53 and CDKN1A. Interacts with TERT, modulating telomere length homeostasis. Ref.11 Ref.14 |
| Tissue specificity | |
| Induction | Frequently induced in esophageal squamous cell carcinoma (SCC) tissues. Ref.13 |
| Post-translational modification | Auto-ubiquitinated; which leads to proteasomal degradation. |
| Sequence similarities | Contains 4 C3H1-type zinc fingers. Contains 1 RING-type zinc finger. |
