Summary

Expression: E.coli
Functional: Yes (ELISA)
Amino Acid Range: Ala117-Ser269

SKU: 4045parent Categories: proteins, Recombinant proteins Tag: active proteins

Weight	1 lbs
Dimensions	9 × 5 × 2 in
express system	E.coli
product tag	C-His-Avi
purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
background	Interleukin-1 beta (IL-1β) is induced by inflammatory signals in a broad number of immune cell types. IL-1β (and IL-18) are the only cytokines which are processed by caspase-1 after inflammasome-mediated activation. IL-1 signaling activates innate immune cells including antigen presenting cells, and drives polarization of CD4 T cells towards T helper type (Th) 1 and Th17 cells.
molecular weight	The protein has a predicted MW of 20.1 kDa same as Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1 EU per μg by the LAL method.

Protein names Interleukin-1 beta (IL-1 beta) (Catabolin)
Gene names IL1B,IL1B IL1F2
Protein family IL-1 family
Mass 9606Da
Function Potent pro-inflammatory cytokine (PubMed:10653850, PubMed:12794819, PubMed:28331908, PubMed:3920526). Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production (PubMed:3920526). Promotes Th17 differentiation of T-cells. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells (PubMed:10653850). Plays a role in angiogenesis by inducing VEGF production synergistically with TNF and IL6 (PubMed:12794819). Involved in transduction of inflammation downstream of pyroptosis: its mature form is specifically released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore (PubMed:33377178, PubMed:33883744). Acts as a sensor of S.pyogenes infection in skin: cleaved and activated by pyogenes SpeB protease, leading to an inflammatory response that prevents bacterial growth during invasive skin infection (PubMed:28331908).
Subellular location Cytoplasm, cytosol. Secreted. Lysosome. Secreted, extracellular exosome. Note=The precursor is cytosolic (PubMed:15192144). In response to inflammasome-activating signals, such as ATP for NLRP3 inflammasome or bacterial flagellin for NLRC4 inflammasome, cleaved and secreted (PubMed:24201029, PubMed:33377178, PubMed:33883744). Mature form is secreted and released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore (PubMed:33883744). In contrast, the precursor form is not released, due to the presence of an acidic region that is proteolytically removed by CASP1 during maturation (PubMed:33883744). The secretion is dependent on protein unfolding and facilitated by the cargo receptor TMED10 (PubMed:32272059).
Tissues Expressed in activated monocytes/macrophages (at protein level).
Structure Monomer. In its precursor form, weakly interacts with full-length MEFV; the mature cytokine does not interact at all (PubMed:17431422). Interacts with integrins ITGAV:ITGBV and ITGA5:ITGB1; integrin-binding is required for IL1B signaling (PubMed:29030430). Interacts with cargo receptor TMED10; the interaction is direct and is required for the secretion of IL1B mature form (PubMed:32272059). Interacts with HSP90AB1; the interaction facilitates cargo translocation into the ERGIC (PubMed:32272059). Interacts with HSP90B1; the interaction facilitates cargo translocation into the ERGIC (PubMed:32272059).
Post-translational modification Activation of the IL1B precursor involves a CASP1-catalyzed proteolytic cleavage. Processing and secretion are temporarily associated.; (Microbial infection) Cleavage by S.pyogenes cysteine protease SpeB promotes its activation independently of CASP1.
