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.
Reactome Pathway
Regulation of PTEN stability and activity (R-HSA-8948751 )
Antigen processing (R-HSA-983168 )
AKT phosphorylates targets in the cytosol (R-HSA-198323 )
