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.

Cellular Localisation Cytoplasm
Cytosol
Secreted
Lysosome
Extracellular Exosome
The Precursor Is Cytosolic
In Response To Inflammasome-Activating Signals
Such As Atp For Nlrp3 Inflammasome Or Bacterial Flagellin For Nlrc4 Inflammasome
Cleaved And Secreted
Mature Form Is Secreted And Released In The Extracellular Milieu By Passing Through The Gasdermin-D (Gsdmd) Pore
In Contrast
The Precursor Form Is Not Released
Due To The Presence Of An Acidic Region That Is Proteolytically Removed By Casp1 During Maturation
The Secretion Is Dependent On Protein Unfolding And Facilitated By The Cargo Receptor Tmed10
