Description:
The encoded protein is a potent proinflammatory cytokine, member of the interleukin 1 cytokine family. It plays an essential role in the regulation of immune responses, inflammatory processes, and haematopoiesis. IL-1α is synthesized as a precursor protein of about 31 kDa. Both the precursor and the cleaved form of IL-1α are biologically active ligands of the cell surface receptor IL-1R1. It functions both as a secreted and as a membrane-bound cytokine. It is present in a wide variety of cells, including the epithelial layers of the gastrointestinal tract, lung, liver, kidney, endothelial cells, astrocytes, activated macrophages and monocytes. IL-1α has been localized into the nucleus where it functions in transcription, suppressing gene expression. Following a signal for cellular necrosis, chromatin-bound IL-1α is released in the cytosolic compartment, where it rapidly initiates a cascade of inflammatory cytokines and chemokines, suggesting a role in the early phase of inflammation. Upon induction of apoptosis, cytosolic IL-1α is sequestered into the nucleus, preventing its inadvertent release and inflammation.
