Interleukin-17A/IL-17A Protein(C-6His) (recombinant human)

Activity: Measured by its ability to induce IL-6 secretion by NIH-3T3 mouse embryonic fibroblast cells.The ED50 for this effect is less than 500 ng/ml. Protein Construction: Recombinant Human Interleukin-17A is produced by our Mammalian expression system and the target gene encoding Gly24-Ala155 is expressed with a 6His tag at the C-terminus. Sequence: Gly24-Ala155. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 19 kDa. Protein function: Interleukin-17 is a potent pro-inflammatory cytokine produced by activated memory T cells. There are at least six members of the IL-17 family in humans and in mice. As IL-17 shares properties with IL-1 and TNF-alpha, it may induce joint inflammation and bone and cartilage destruction. This cytokine is found in synovial fluids of patients with rheumatoid arthritis, and produced by rheumatoid arthritis synovium. It increases IL-6 production, induces collagen degradation and decreases collagen synthesis by synovium and cartilage and proteoglycan synthesis in cartilage. IL-17 is also able to increase bone destruction and reduce its formation. Blocking of interleukin-17 with specific inhibitors provides a protective inhibition of cartilage and bone degradation. Protein function: Ligand for IL17RA and IL17RC (PubMed:17911633). The heterodimer formed by IL17A and IL17F is a ligand for the heterodimeric complex formed by IL17RA and IL17RC (PubMed:18684971). Involved in inducing stromal cells to produce proinflammatory and hematopoietic cytokines (PubMed:8676080). [The UniProt Consortium]
