Function

E3 ubiquitin ligase involved in the retrotranslocation and turnover of membrane and secretory proteins from the ER through a set of processes named ER-associated degradation (ERAD). This process acts on misfolded proteins as well as in the regulated degradation of correctly folded proteins. Enhances ionizing radiation-induced p53/TP53 stability and apoptosis via ubiquitinating MDM2 and AKT1 and decreasing AKT1 kinase activity through MDM2 and AKT1 proteasomal degradation. Regulates ER stress-induced autophagy, and may act as a tumor suppressor. {ECO:0000269PubMed:17314412, ECO:0000269PubMed:21333377, ECO:0000269PubMed:22178386}.

Subcellular Localization

Endoplasmic reticulum membrane {ECO:0000269PubMed:17314412, ECO:0000269PubMed:21333377, ECO:0000269PubMed:22178386}; Single-pass membrane protein {ECO:0000269PubMed:17314412, ECO:0000269PubMed:21333377, ECO:0000269PubMed:22178386}. Note=Concentrates and colocalizes with p62/SQSTM1 and ZFYVE1 at the perinuclear endoplasmic reticulum.
