Target description
Interleukin-1 alpha (UniProt: P01582; also known as IL-1 alpha) is encoded by the Il1a gene (Gene ID: 16175) in mouse. IL-1 is constitutively expressed in several healthy tissues in a steady state and its expression can be increased in response to a number of stimuli. Absolute amounts of IL-1 vary among cell types, but barrier cells, such as endothelial and epithelial cells, express higher amounts at steady state. IL-1 is synthesized with a propeptide (aa 1-112) and is post-translationally modified by phosphorylation at serine 90, myristoylation on lysine 82, and acetylation on lysine 82. After synthesis, pro- IL-1 is localized into the nucleus, cytosol or lysosomal compartment or is displayed on the outer leaflet of the plasma membrane. Its intracellular localization can change in response to specific stimuli. Pro- IL-1 can also be cleaved by calpain to generate IL-1 -N-terminal domain (NTP) and a mature C-terminal IL-1 form. The C-terminal domain is catalytically active and is capable of signaling via IL-1R. Both IL-1 -NTP and pro- IL-1 contains a functional NLS signal and bind HAX1 to allow translocation into the nucleus. In the nucleus, IL-1 -NTP binds transcription regulation factors and activates expression of proinflammatory cytokines and chemokines independently of IL-1R1 signaling. The biological functions of IL-1 also involve stimulation of thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity.
