Component of a VCP\/p97-AMFR\/gp78 complex that participates in the final step of endoplasmic reticulum-associated degradation (ERAD) (PubMed: 10456327, PubMed: 11724934, PubMed: 19103148, PubMed: 24424410). The VCP\/p97-AMFR\/gp78 complex is involved in the sterol-accelerated ERAD degradation of HMGCR through binding to the HMGCR-INSIG1 complex at the ER membrane (PubMed: 16168377, PubMed: 22143767). In addition, interaction of AMFR with AUP1 facilitates interaction of AMFR with ubiquitin-conjugating enzyme UBE2G2 and ubiquitin ligase RNF139, leading to sterol-induced HMGCR ubiquitination (PubMed: 23223569). The ubiquitinated HMGCR is then released from the ER into the cytosol for subsequent destruction (PubMed: 16168377, PubMed: 22143767, PubMed: 23223569). In addition to ubiquitination on lysine residues, catalyzes ubiquitination on cysteine residues: together with INSIG1, mediates polyubiquitination of SOAT2\/ACAT2 at 'Cys-277', leading to its degradation when the lipid levels are low (PubMed: 28604676). Catalyzes ubiquitination and subsequent degradation of INSIG1 when cells are depleted of sterols (PubMed: 17043353). Mediates polyubiquitination of INSIG2 at 'Cys-215' in some tissues, leading to its degradation (PubMed: 31953408). Also regulates ERAD through the ubiquitination of UBL4A a component of the BAG6\/BAT3 complex (PubMed: 21636303). Also acts as a scaffold protein to assemble a complex that couples ubiquitination, retranslocation and deglycosylation (PubMed: 21636303). Mediates tumor invasion and metastasis as a receptor for the GPI\/autocrine motility factor (PubMed: 10456327). In association with LMBR1L and UBAC2, negatively regulates the canonical Wnt signaling pathway in the lymphocytes by promoting the ubiquitin-mediated degradation of CTNNB1 and Wnt receptors FZD6 and LRP6 (PubMed: 31073040).\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"Default Title","offer_id":56592656957813,"sku":"BT-E5210Hu-96T","price":370.98,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/2671\/1640\/files\/ELISA_Kit_main_1.jpg?v=1766393459","url":"https:\/\/www.labcart.com\/de\/products\/human-e3-ubiquitin-protein-ligase-amfr-amfr-elisa-kit-96t","provider":"LabCart Life Science","version":"1.0","type":"link"}
