Rabbit Anti-Human IL1B / IL1F2 Monoclonal Antibody

Antigen Description :	Interleukin 1 (IL-1) is a family of polypeptide cytokines consisting of two agonists, IL-1alpha (IL-1F1) and IL-1beta (IL-1F2) encoded by two distinct genes and perform identical biological functions. IL1α and IL1β binds directly to a high-affinity receptor complex of IL1 RI and IL1 R AcP to initiate the signal transduction. IL1RII also binds to IL1β with high affinity, but on contrast, IL1β activity is inhibited since IL1RII exists as a decoy receptor and negative regulator.IL1R antgonist (IL1RA), also a member of IL-1 family, is identified to interact with IL1R1, preventing IL1α and IL1β to exert actions. IL1β is produced by a variety of cell types, and capable of stimulating thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. Also identified as endogenous pyrogens, IL-1 are involved in the immune and inflammatory responses, and are reported to stimulate the release of prostaglandin and collagenase. IL1β is encoded as a inactive precusor of 269 amino acids with a 116 aa propeptide which is cleaved intracellularly by the cysteine protease, IL1β converting enzyme (Caspase1/ICE) to generate the biologically active cytokine. Lacking of a specific hydrophobic segment suggests that IL-1 is released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins.
