OS-9 is an N-glycosylated ER resident protein that harbors a mannose-6-phosphate receptor homology (MRH) domain and plays a critical role in mammalian ER quality control, in part, by functioning as a lectin. There are two major isoforms of OS-9 (OS-9-1, OS-9-2) that are generated through alternative splicing of mRNA (2). The expression of both OS-9 isoforms is enhanced upon activation of the IRE1\/XBP1 pathway in cells exposed to acute ER stress. It is postulated that OS-9 serves as a retention factor for glycosylated and nonglycosylated, misfolded proteins, preventing their progression through the secretory pathway (3,4). Furthermore, OS-9 promotes the removal of misfolded proteins from the ER lumen and their subsequent proteasome-dependent degradation via its association with the Hrd1-SEL1L ubiquitin ligase complex (5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nAmplified in osteosarcoma 9; endoplasmic reticulum lectin 2; ERLEC2; erlectin 2; OS-9; OS9; OS9 endoplasmic reticulum lectin; osteosarcoma amplified 9, endoplasmic reticulum associated protein; osteosarcoma amplified 9, endoplasmic reticulum lectin; Protein OS-9\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 83,97\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46797573456041,"sku":"12497T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-12497t","provider":"Iright","version":"1.0","type":"link"}
