General annotation (Comments)

Function	E3 ubiquitin-protein ligase which can target both itself and other proteins including CD3D and APOB for proteasomal degradation. Mediates polyubiquitination of CYP3A4. Specific receptor for the autocrine motility factor. Mediates tumor invasion and metastasis. Component of a complex required to couple deglycosylation and proteasome-mediated degradation of misfolded proteins in the endoplasmic reticulun that are retrotranslocated in the cytosol By similarity. Promotes ubiquitination of misfolded proteins such as mutant CFTR; proposed to mediate sequential ubiquitination by recognizing already ubiquitin-conjugated substrates and to cooperate with E3 ubiquitin-protein ligase RNF5. Ref.3 Ref.6
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Interacts with UBE2G2/UBC7 through a region distinct from the RING finger. Component of a complex required to couple retrotranslocation, ubiquitination and deglycosylation composed of NGLY1, SAKS1, AMFR, VCP and RAD23B. Interacts with RNF5. Ref.4 Ref.6 UniProtKB Q9UKV5
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.
Tissue specificity	Expressed in heart, brain, liver, lung, skeletal muscle, kidney and testis. Not detected in spleen. Ref.1
Domain	The CUE domain is required for recognition of misfolded proteins such as mutant CFTR.
Sequence similarities	Contains 1 CUE domain. Contains 1 RING-type zinc finger.
