Protein Information (annotations from UniProt)

Database IDHIV0002056
UniProt IDQ13438
Primary gene name(s)OS9
Synonym gene name(s)unknown
Protein nameProtein OS-9
Protein functionLectin which functions in endoplasmic reticulum, ER quality control and ER-associated degradation, ERAD. May bind terminally misfolded non-glycosylated proteins as well as improperly folded glycoproteins, retain them in the ER, and possibly transfer them to the ubiquitination machinery and promote their degradation. Possible targets include TRPV4. {ECO:0000269|PubMed:17932042, ECO:0000269|PubMed:18264092, ECO:0000269|PubMed:18417469, ECO:0000269|PubMed:19084021, ECO:0000269|PubMed:19346256, ECO:0000269|PubMed:21172656}.
Subcellular locationEndoplasmic reticulum lumen {ECO:0000269|PubMed:18264092, ECO:0000269|PubMed:18417469, ECO:0000269|PubMed:19084021}.
