Biophys. Acta 1823:316-326(2012). CC -!- FUNCTION: E3 ubiquitin ligase involved in the retrotranslocation CC and turnover of membrane and secretory proteins from the ER CC through a set of processes named ER-associated degradation (ERAD). CC This process acts on misfolded proteins as well as in the CC regulated degradation of correctly folded proteins. Enhances CC ionizing radiation-induced p53/TP53 stability and apoptosis via CC ubiquitinating MDM2 and AKT1 and decreasing AKT1 kinase activity CC through MDM2 and AKT1 proteasomal degradation. Regulates ER CC stress-induced autophagy, and may act as a tumor suppressor. CC {ECO:0000269|PubMed:17314412, ECO:0000269|PubMed:21333377, CC ECO:0000269|PubMed:22178386}. CC -!- PATHWAY: Protein modification; protein ubiquitination. CC -!- SUBUNIT: Interacts (via C-terminal domain) with VCP. Interacts CC with AKT1; the interaction ubiquitinates AKT1 and leads to its CC proteasomal degradation. Interacts with MDM2; the interaction CC ubiquitinates AKT1 and leads to its proteasomal degradation. CC Interacts with p62/SQSTM1. {ECO:0000269|PubMed:17314412, CC ECO:0000269|PubMed:21333377, ECO:0000269|PubMed:22178386}. CC -!- INTERACTION: CC Q53SE7:FLJ13057; NbExp=3; IntAct=EBI-9867345, EBI-10172181; CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane CC {ECO:0000269|PubMed:17314412, ECO:0000269|PubMed:21333377, CC ECO:0000269|PubMed:22178386}; Single-pass membrane protein CC {ECO:0000269|PubMed:17314412, ECO:0000269|PubMed:21333377, CC ECO:0000269|PubMed:22178386}. Note=Concentrates and colocalizes CC with p62/SQSTM1 and ZFYVE1 at the perinuclear endoplasmic CC reticulum. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=3; CC Name=1; Synonyms=Alpha; CC IsoId=O60858-1; Sequence=Displayed; CC Name=2; Synonyms=Beta; CC IsoId=O60858-2; Sequence=VSP_005746, VSP_005747; CC Name=3; CC IsoId=O60858-3; Sequence=VSP_038142; CC -!- DOMAIN: The coiled-coil domain is required for the induction of CC autophagy during endoplasmic reticulum (ER) stress. CC -!- DOMAIN: The RING-type zinc finger is required for auto- CC polyubiquitination. CC -!- DOMAIN: The C-terminal domain transmembrane domain is CC indispensable for the localization to the ER. CC -!- PTM: Auto-ubiquitinated; requires the RING-type zinc finger. Auto- CC polyubiquitination leads to proteasomal degradation.
