Lectin 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. Belongs to the OS-9 family. 4 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Endoplasmic reticulum
Cellular Component: endoplasmic reticulum lumen
Molecular Function: protein binding; protease binding; glycoprotein binding
Biological Process: ER-associated protein catabolic process; protein ubiquitination during ubiquitin-dependent protein catabolic process; protein ubiquitination; protein retention in ER; protein targeting
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
