Physical State | Liquid |
Immunogen | KLH conjugated synthetic peptide derived from human OS9 |
Epitope Specificity | 101-200/667 |
Isotype | IgG |
Purity | affinity purified by Protein A |
Buffer | 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. |
SUBCELLULAR LOCATION | ndoplasmic reticulum lumen. |
SIMILARITY | Belongs to the OS-9 family. Contains 1 PRKCSH domain. |
SUBUNIT | Probably part of the HRD1 ubiquitin ligase complex composed at least of SYVN1/HRD1 and SEL1L with which it interacts directly. Through this complex it may interact with ERLEC1 and HSPA5. Interacts with DERL2. Interacts with HSP90B1 and CREB3. |
Post-translational modifications | Intramolecular disulfide bonds. Isoform 1 and isoform 2 are N-glycosylated. |
Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. |
Background Descriptions | 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. |
Gene ID | 10956 |

Other Names | Protein OS-9, Amplified in osteosarcoma 9, OS9 |
Target/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 is the major isoform detected in all cell types examined. |
Dilution | WB=1:500-2000,IHC-P=1:100-500,IHC-F=1:100-500,IF=1:100-500,ELISA=1:5000-10000 |
Format | 0.01M TBS(pH7.4), 0.09% (W/V) sodium azide and 50% Glyce |
Storage | Store at -20 ℃ for one year. Avoid repeated freeze/thaw cycles. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody the antibody is stable for at least two weeks at 2-4 ℃. |

Function | Lectin component of the HRD1 complex, which functions in endoplasmic reticulum (ER) quality control and ER-associated degradation (ERAD) (PubMed:18264092, PubMed:18417469, PubMed:19084021, PubMed:19346256, PubMed:21172656, PubMed:24899641). 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 (PubMed:18264092, PubMed:18417469, PubMed:19084021, PubMed:19346256, PubMed:21172656, PubMed:24899641). Possible targets include TRPV4 as well as hyperglycosylated HSP90B1 (PubMed:17932042). |
Cellular Location | Endoplasmic reticulum lumen |
Tissue Location | Ubiquitously expressed (PubMed:8634085). Found as well in all tumor cell lines analyzed, amplified in sarcomas (PubMed:8634085). Highly expressed in osteosarcoma SJSA-1 and rhabdomyosarcoma Rh30 cell lines (PubMed:8634085) |
