Function IL-6 is a cytokine known to have many functions which include stimulating cells that give rise to blood cells and cells that function in the immune system. IL-6 aids in the antibody-mediated immunity component of the adaptive immune system by targeting cells that secrete antibodies such as B lymphocytes. It also plays in cell-mediated immunity by targeting cells such as T lymphocytes. It turns and enhances the colony of cells producing blood cells. It also aids in the production of the proteins that flux in plasma concentration in response to inflammation, which are known as acute phase response proteins. Disease IL-6 has been found to be involved with the maintenance of bone homeostasis, as an increase in IL-6 levels has strongly reported in illnesses such as Paget’s disease and myeloma, where significant bone loss occurs. IL-6 has also been implicated in Castleman Disease. Relevance IL-6 is produced is produced by wide range of cells that include not just cells of the immune system. Its production is induced by immune response, but can be affected by various antigenic factors. Structural highlights This is a sample scene created with SAT to color by Group, and another to make a transparent representation of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes. The structure of IL-6 is composed of four helices: A, B, C, and D. Helices A and B run in opposite direction to helices C and D. Helix A is connected to B which is connected to C; then C is connected to D. Here you are able to get a clear view of the four helices that form IL-6. Here you are able to get a clear view of Helix A. Here you are able to get a clear view of Helix B. Here you are able to get a view of the water structure in the region between the D helix and the A-B loop of IL-6. The water molecules are shown as red spheres. The A-B loop is shown in brown with a yellow disulfide linkage near F74 which is displayed in pink. The D helix is shown in black. Q175 is shown in green. R179 is shown in blue. Here you are able to get a clear view of the disulfide linkage between Helix A and Helix B.
