[https://www.uniprot.org/uniprot/HRD1_YEAST HRD1_YEAST] E3 ubiquitin-protein ligase which accepts ubiquitin specifically from endoplasmic reticulum-associated UBC1 and UBC7 E2 ligases, and transfers it to substrates promoting their degradation. Mediates the degradation of endoplasmic reticulum proteins (ERQC), also called ER-associated degradation (ERAD). Component of the HRD1 ubiquitin ligase complex, which is part of the ERAD-L and ERAD-M pathways responsible for the rapid degradation of soluble lumenal and membrane proteins with misfolded lumenal domains (ERAD-L), or ER-membrane proteins with misfolded transmembrane domains (ERAD-M). ERAD-L substrates are ubiquitinated through HRD1 in conjunction with the E2 ubiquitin-conjugating enzymes UBC1 and UBC7-CUE1. Ubiquitinated substrates are then removed to the cytosol via the action of the UFD1-NPL4-CDC48/p97 (UNC) AAA ATPase complex and targeted to the proteasome. ERAD-M substrates are processed by the same HRD1-HRD3 core complex, but only a subset of the other components is required for ERAD-M.<ref>PMID:10218484</ref> <ref>PMID:10547371</ref> <ref>PMID:10793145</ref> <ref>PMID:11018054</ref> <ref>PMID:11139575</ref> <ref>PMID:11146622</ref> <ref>PMID:11390656</ref> <ref>PMID:16619026</ref> <ref>PMID:16873066</ref> <ref>PMID:20005842</ref> <ref>PMID:21074049</ref> <ref>PMID:8970163</ref> <ref>PMID:9437001</ref>
