The gene IL17A (interleukin 17A), also referred to as IL-17, is mapped to human chromosome 6p12.2. The gene contain three exons and encodes a proinflammatory cytokine produced by activated T cells.
The cytokine interleukin 17A is involved in the activation of proinflammatory cytokines, chemokines, and cell adhesion molecules in several cell types such as, macrophages, dendritic cells, T cells, synovial cells, and endothelial cells. Overexpression of this protein has been associated with rheumatoid arthritis, systemic lupus erythematosus, Behcet′s disease, allograft rejection, nephritic syndrome, asthma, and multiple sclerosis. In mice, it has been observed to be implicated in the development of allergic and autoimmune diseases. Polymorphism in IL17A gene has been associated with lung cancer.
Interleukin-17A Human Recombinant produced in E.Coli is a homodimeric, non-glycosylated polypeptide chain containing a total of 264 amino acids (2 chains of 132 aa) and having a molecular mass of 31kDa.
The IL-17 is purified by proprietary chromatographic techniques.
IL17 is a proinflammatory cytokine produced by activated T cells. IL-17 regulates the activities of NF-kappaB and mitogen-activated protein kinases. Interleukin-17 can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO). High levels of IL-17 are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis and multiple sclerosis.
