Function

[UBC7_SCHPO] Catalyzes the covalent attachment of ubiquitin to other proteins. Functions in degradation of misfolded or regulated proteins localized in the endoplasmic reticulum (ER) lumen or membrane via the ubiquitin-proteasome system. Cognate E2 conjugating enzyme for the doa10 ubiquitin ligase complex, which is part of the ERAD-C pathway responsible for the rapid degradation of membrane proteins with misfolded cytoplasmic domains, and 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) (By similarity). Together with hrd1, required for the degradation of the transcription factor sre1 precursor in the absence of its binding partner scp1. Has a role in the formation of chromatin structures that influence the localization of transcriptional silencing factors.[PROSITE-ProRule:PRU00388]^{[1] [2]}
