Research Backgrounds
E3-ubiquitin ligase; acts as a negative regulator of the cell proliferation through mechanisms involving G2/M arrest and cell death. Required for MHC class I ubiquitination in cells expressing the cytomegalovirus protein US2 before dislocation from the endoplasmic reticulum (ER). Affects SREBP processing by hindering the SREBP/SCAP complex translocation from the ER to the Golgi, thereby reducing SREBF2 target gene expression. Required for INSIG1 ubiquitination. May be required for EIF3 complex ubiquitination. May function as a signaling receptor.
Autoubiquitinated. Ubiquitination is induced by sterol and leads to ist degradation via the ubiquitin-proteasome pathway.
Endoplasmic reticulum membrane>Multi-pass membrane protein.
Highly expressed in testis, placenta and adrenal gland. Moderate expression in heart, brain, liver, skeletal muscle and pancreas, and low expression in lung and kidney.
Interacts with MHC class I and HM13. Interacts with VHL. Component of SCAP/SREBP complex composed of SREBF2, SCAP and RNF139; the complex hampers the interaction between SCAP and SEC24B, thereby reducing SREBF2 proteolytic processing. Interacts with SREBF2 (via C-terminal domain). Interacts with SCAP; the interaction inhibits the interaction of SCAP with SEC24B and hampering the ER to Golgi transport of the SCAP/SREBP complex. Interacts with SEC24B. Interacts with INSIG1 and INSIG2. Interacts with EIF3F and EIF3H; the interaction leads to protein translation inhibitions in a ubiquitination-dependent manner. Interacts with XBP1 isoform 1; the interaction induces ubiquitination and degradation of XBP1 isoform 1.
The RING-type zinc finger domain mediates ubiquitin ligase activity.
