    • IHC image of CSB-RA959292A0HU diluted at 1:100 and staining in paraffin-embedded human pancreatic tissue 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.

靶點(diǎn)詳情

  • 功能：
    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.

    2. 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
    3. EDEM2 and OS-9 are required for ER-associated degradation of non-glycosylated sonic hedgehog PMID: 24910992
    4. Unique regions mediate the interaction between OS-9 and GRP94. PMID: 24899641

    8. 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
    9. It regulates endoplasmic reticulum-associated degradation. (review) PMID: 21404621
    10. The OS-9 specifically recognizes Manalpha1,6Manalpha1,6Man residues on the processed C-arm through the continuous double tryptophan (WW) motif. PMID: 21172656

    13. OS-9 regulates the secretory transport of TRPV4 and appears to protect TRPV4 subunits from the precocious ubiquitination and ER-associated degradation. PMID: 17932042
    14. OS-9 and GRP94 deliver mutant alpha1-antitrypsin to the Hrd1-SEL1L ubiquitin ligase complex for ERAD PMID: 18264092

    17. 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
    18. 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
