DVS 27 was identifed as a gene that is upregulated in vasospastic cerebral arteries. NF-HEV was described as a nuclear factor that is preferentially expressed in the endothelial cells of high endothelial venules relative to endothelial cells from other tissues. IL-33 was identified based on sequence and structural homology with IL-1 family cytokines. DVS 27, NF-HEV, and IL-33 share 100% amino acid sequence identity. IL-33 is constitutively expressed in smooth muscle and airway epithelia. It is upregulated in arterial smooth muscle, dermal fibroblasts, and keratinocytes following IL-1 alpha or IL-1 beta stimulation. Similar to IL-1, IL-33 can be cleaved in vitro by caspase-1, generating an N-terminal fragment that is slightly shorter than the C-terminal fragment. The N-terminal portion of full length IL-33 contains a predicted bipartite nuclear localization sequence and a homeodomain-like helix-turn-helix DNA binding domain. By immunofluorescence, full length IL-33 localizes to the nucleus in HUVECs and transfectants. The C-terminal fragment, corresponding to mature IL-33, binds and triggers signaling through mast cell IL-1 R4\/ST2L, a longtime orphan receptor involved in the augmentation of Th2 cell responses. A ternary signaling complex is formed by the subsequent association of IL-33 and ST2L with IL-1R AcP. Stimulation of Th2 polarized lymphocytes with mature IL-33 in vitro induces IL-5 and IL-13 secretion. In vivo administration of mature IL-33 promotes increased production of IL-5, IL-13, IgE, and IgA, as well as splenomegaly and inflammatory infiltration of mucosal tissues. Full length and mature human IL-33 share 52 ‑ 58% aa sequence identity with mouse and rat IL-33. Human IL-33 shares less than 20% aa sequence identity with other IL-1 family proteins.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e:1 mg\/mL\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e:Recombinant Human IL-33 Protein\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBuffer\u003c\/b\u003e:0.2 μm filtered solution in PBS\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification method\u003c\/b\u003e:Protein A\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDilution\u003c\/b\u003e:IHC-P 1:500-1:2000;\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCalculated MW\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e:\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48644718329956,"sku":"AN300184P","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_84689dc0-7b79-4247-b822-2fc73778738c.jpg?v=1782651854","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/recombinant-il-33-monoclonal-antibody","provider":"GeneBio ","version":"1.0","type":"link"}
