IL 1 alpha
Interleukin 1 alpha
Preinterleukin 1 alpha
Pro interleukin 1 alpha
FunctionProduced by activated macrophages, IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells.
Sequence similaritiesBelongs to the IL-1 family.
DomainThe similarity among the IL-1 precursors suggests that the amino ends of these proteins serve some as yet undefined function.
Cellular localizationSecreted. The lack of a specific hydrophobic segment in the precursor sequence suggests that IL-1 is released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins.
