IHC image of CSB-PA613402LA01HU diluted at 1:50 and staining in paraffin-embedded human Lung cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB. Secondary antibody only control: uses 1% BSA instead of primary antibody

Target Background

Function(From Uniprot)

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 References into Functions

The endoplasmic reticulum-associated protein, OS-9, behaves as a lectin in targeting the immature calcium-sensing receptor. PMID:28419469
OS-9 up-regulates occludin and claudin-1 by activating the MAP kinase (MAPK) pathway, and thus protects the epithelial barrier function of Caco-2 monolayer under hypoxia condition. PMID:25999789
EDEM2 and OS-9 are required for ER-associated degradation of non-glycosylated sonic hedgehog PMID:24910992
Unique regions mediate the interaction between OS-9 and GRP94. PMID:24899641
It delivers mutant neuroserpin to ERAD by recognition of glycan side chains and provide the first in vivo proof of involvement of ERAD in degradation of mutant neuroserpin. PMID:24795221
long non-coding RNA ENST00000480739 suppresses tumour cell invasion by regulating OS-9 and HIF-1alpha in pancreatic ductal adenocarcinoma. PMID:25314054
Data indicate that the interaction of OS-9 and XTP3-B with CD147(CG) was inhibited by mutations to conserved residues in their lectin domains. PMID:23097496
OS-9 plays no direct functional role in HIF degradation since physical interaction of OS-9 with oxygen sensing HIF prolyl hydroxylases cannot occur in vivo due to their different subcellular localization PMID:21559462
It regulates endoplasmic reticulum-associated degradation. (review) PMID:21404621
The OS-9 specifically recognizes Manalpha1,6Manalpha1,6Man residues on the processed C-arm through the continuous double tryptophan (WW) motif. PMID:21172656

Identification of a peptide, resulting from a point mutation in gene OS-9, recognized by cytolytic T lymphocytes on a human melanoma. PMID:12747754
OS-9 regulates the secretory transport of TRPV4 and appears to protect TRPV4 subunits from the precocious ubiquitination and ER-associated degradation. PMID:17932042
OS-9 and GRP94 deliver mutant alpha1-antitrypsin to the Hrd1-SEL1L ubiquitin ligase complex for ERAD PMID:18264092
Xbp1-responsive OS-9 variants in the mammalian endoplasmic reticulum inhibit secretion of misfolded protein conformers and enhancing their disposal PMID:18417469
OS9 is critically involved in the modulation of ER-to-Golgi transport of DC-STAMP in response to TLR triggering, suggesting a novel role for OS9 in myeloid differentiation and cell fusion. PMID:18952287
OS-9 recognises terminally misfolded proteins via polypeptide-based rather than glycan-based signals, but is only required for transferring those bearing N-glycans to the ubiquitination machinery. PMID:19084021
model for mannose trimming and the requirement for OS-9 lectin activity in glycoprotein ERAD in which N-glycans lacking the terminal mannose from the C branch are recognized by OS-9 and targeted for degradation PMID:19346256
