| Tissue Specificity | Ubiquitously expressed. Found as well in all tumor cell lines analyzed, amplified in sarcomas. Highly expressed in osteosarcoma SJSA-1 and rhabdomyosarcoma Rh30 cell lines. Isoform 2: Isoform 2 is the major isoform detected in all cell types examined. |
| Post Translational Modifications | Intramolecular disulfide bonds. Isoform 1 and isoform 2 are N-glycosylated. |
| Function | Lectin component of the HRD1 complex, which functions in endoplasmic reticulum (ER) quality control and ER-associated degradation (ERAD). Specifically recognizes and binds improperly folded glycoproteins as well as hyperglycosylated proteins, retain them in the ER, and transfers them to the ubiquitination machinery and promote their degradation. Possible targets include TRPV4 as well as hyperglycosylated HSP90B1. |
