Protein Information (annotations from UniProt)

Database IDHIV0001280
UniProt IDQ15011
Primary gene name(s)HERPUD1
Synonym gene name(s)HERP, KIAA0025, MIF1
Protein nameHomocysteine-responsive endoplasmic reticulum-resident ubiquitin-like domain member 1 protein
Protein functionComponent of the endoplasmic reticulum quality control, ERQC system also called ER-associated degradation, ERAD involved in ubiquitin-dependent degradation of misfolded endoplasmic reticulum proteins. Could enhance presenilin-mediated beta-amyloid protein 40 generation. Binds to ubiquilins and this interaction is required for efficient degradation of CD3D via the ERAD pathway, PubMed:18307982. {ECO:0000269|PubMed:16289116, ECO:0000269|PubMed:18307982}.
Subcellular locationEndoplasmic reticulum membrane {ECO:0000269|PubMed:10922362};
Multi-pass membrane protein {ECO:0000269|PubMed:10922362}.
