Previous GeneCards Identifiers for IL1B Gene
The protein encoded by this gene is a member of the interleukin 1 cytokine family. This cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis. The induction of cyclooxygenase-2 (PTGS2/COX2) by this cytokine in the central nervous system (CNS) is found to contribute to inflammatory pain hypersensitivity. This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. [provided by RefSeq, Jul 2008]
GeneCards Summary for IL1B Gene
IL1B (Interleukin 1 Beta) is a Protein Coding gene. Diseases associated with IL1B include Gastric Cancer, Hereditary Diffuse and Toxic Shock Syndrome. Among its related pathways are Th1 Differentiation Pathway and Hematopoietic cell lineage. Gene Ontology (GO) annotations related to this gene include protein domain specific binding and interleukin-1 receptor binding. An important paralog of this gene is IL1RN.
UniProtKB/Swiss-Prot Summary for IL1B Gene
Potent proinflammatory 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 (PubMed:10653850).
Cytokines are proteinaceous signaling compounds that are major mediators of the immune response. They control many different cellular functions including proliferation, differentiation and cell survival/apoptosis but are also involved in several pathophysiological processes.
