CC -!- FUNCTION: E3 ubiquitin-protein ligase which accepts ubiquitin CC specifically from endoplasmic reticulum-associated UBC1 and UBC7 E2 CC ligases, and transfers it to substrates promoting their degradation. CC Mediates the degradation of endoplasmic reticulum proteins (ERQC), also CC called ER-associated degradation (ERAD). Component of the HRD1 CC ubiquitin ligase complex, which is part of the ERAD-L and ERAD-M CC pathways responsible for the rapid degradation of soluble lumenal and CC membrane proteins with misfolded lumenal domains (ERAD-L), or ER- CC membrane proteins with misfolded transmembrane domains (ERAD-M). In CC ERAD-L, facilitates retrotranslocation of misfolded proteins from the CC ER lumen through the ER membrane in conjunction with DER1 CC (PubMed:32327568). Both proteins have lateral gates facing each other CC which form a channel through the ER membrane and which distort the CC membrane region between the lateral gates, making it much thinner than CC a normal phospholipid bilayer (PubMed:32327568). Substrates insert into CC the membrane as a hairpin loop with one strand interacting with DER1 CC and the other with HRD1. ERAD-L substrates are ubiquitinated through CC HRD1 in conjunction with the E2 ubiquitin-conjugating enzymes UBC1 and CC UBC7-CUE1. Ubiquitinated substrates are then removed to the cytosol via CC the action of the CDC48-NPL4-UFD1 ATPase complex and targeted to the CC proteasome. ERAD-M substrates are processed by the same HRD1-HRD3 core CC complex, but only a subset of the other components is required for CC ERAD-M. {ECO:0000269|PubMed:10218484, ECO:0000269|PubMed:10547371, CC ECO:0000269|PubMed:10793145, ECO:0000269|PubMed:11018054, CC ECO:0000269|PubMed:11139575, ECO:0000269|PubMed:11146622, CC ECO:0000269|PubMed:11390656, ECO:0000269|PubMed:16619026, CC ECO:0000269|PubMed:16873066, ECO:0000269|PubMed:20005842, CC ECO:0000269|PubMed:21074049, ECO:0000269|PubMed:32327568, CC ECO:0000269|PubMed:8970163, ECO:0000269|PubMed:9437001}. CC -!- CATALYTIC ACTIVITY: CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L- CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.; CC EC=2.3.2.27; CC -!- PATHWAY: Protein modification; protein ubiquitination. CC -!- SUBUNIT: Monomer (PubMed:32327568). Has also been shown to form CC homodimers (PubMed:28682307). However, dimer assembly is likely to be CC non-physiological (PubMed:32327568). Forms homooligomers in a USA1- CC dependent manner (PubMed:20005842, PubMed:21074049). However, can CC function as a monomer in ERAD-L so the role of USA1-dependent CC oligomerization remains unclear (PubMed:32327568). Component of the CC HRD1 ubiquitin ligase complex which contains the E3 ligase HRD1, its CC cofactors HRD3, USA1 and DER1, substrate recruiting factor YOS9 and CC CDC48-binding protein UBX2 (PubMed:16873066). Within the complex, CC interacts directly with HRD3 and USA1 and indirectly with DER1 CC (PubMed:11018054, PubMed:16619026, PubMed:20005842, PubMed:21074049, CC PubMed:28682307). In ERAD-L, HRD3 and YOS9 jointly bind misfolded CC glycoproteins in the endoplasmic reticulum (ER) lumen CC (PubMed:32327568). Movement of ERAD-L substrates through the ER CC membrane is facilitated by HRD1 and DER1 which have lateral gates CC facing each other and which distort the membrane region between the CC lateral gates, making it much thinner than a normal phospholipid CC bilayer (PubMed:32327568). Substrates insert into the membrane as a CC hairpin loop with one strand interacting with DER1 and the other with CC HRD1 (PubMed:32327568). The HRD1 complex interacts with the CC heterotrimeric CDC48-NPL4-UFD1 ATPase complex which is recruited by CC UBX2 via its interaction with CDC48 and which moves ubiquitinated CC substrates to the cytosol for targeting to the proteasome CC (PubMed:16873066, PubMed:16619026). The HRD1 complex interacts with the CC ERAD substrates HMG1 and HMG2 (PubMed:11390656). Interacts with the CC associated E2 ubiquitin conjugating enzymes UBC1 and UBC7 with its CC membrane anchor CUE1 (PubMed:11146622). {ECO:0000269|PubMed:11018054, CC ECO:0000269|PubMed:11146622, ECO:0000269|PubMed:11390656, CC ECO:0000269|PubMed:16619026, ECO:0000269|PubMed:16873066, CC ECO:0000269|PubMed:20005842, ECO:0000269|PubMed:21074049, CC ECO:0000269|PubMed:28682307, ECO:0000269|PubMed:32327568}.
