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.

Biological Context

Subcellular Location: Cytoplasm, cytosol; Secreted; Lysosome; Secreted, extracellular exosome

Product Specifications

Recombinant Sheep Interleukin-1 beta (IL1B) is a recombinant protein from Ovis aries (Sheep), expressed in E.coli, covering amino acids 114-266aa, with N-terminal 6xHis-tagged tag, molecular weight 21.7kDa, purity Greater than 90% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

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

Subcellular Location

Cytoplasm, cytosol; Secreted; Lysosome; Secreted, extracellular exosome

Subunit

Monomer. In its precursor form, weakly interacts with full-length MEFV; the mature cytokine does not interact at all. Interacts with integrins ITGAV:ITGBV and ITGA5:ITGB1; integrin-binding is required for IL1B signaling. Interacts with cargo receptor TMED10; the interaction is direct and is required for the secretion of IL1B mature form. Interacts with HSP90AB1; the interaction facilitates cargo translocation into the ERGIC. Interacts with HSP90B1; the interaction facilitates cargo translocation into the ERGIC
