Recombinant Human IL-1 beta Protein is produced by E. coli expression system. The target protein is expressed with sequence (Ala117-Ser269) of human IL-1 beta (Accession #NP_000567.1) fused with an initial Met at the N-terminus and a 6×His tag at the |
| Tissue Specificity | Expressed in activated monocytes/macrophages (at protein level). |
| Post Translational Modifications | 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. |
| Function | Potent pro-inflammatory cytokine. 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. Promotes Th17 differentiation of T-cells. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells. Plays a role in angiogenesis by inducing VEGF production synergistically with TNF and IL6. 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. 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. |
