Recombinant human Interleukin-6 (IL6) protein (CI-460-33)


Human Interleukin-6 (IL-6) plays a role in the mediation of the inflammatory and immune response initiated by infection or injury. IL-6 acts on B cells by stimulating differentiation and antibody secretion. IL-6 also exhibits growth factor activity for mature thymic or peripheral T cells, and enhances the differentiation of cytotoxic T cells in the presence of IL-2 or IFNt. This glycoprotein is composed of 184 amino acid residues, and has a 42% homology with murine IL-6. Human Interleukin-6 (RECOMBINANT) is produced in genetically engineered Spodoptera frugiperda insect cells (Sf9) infected with recombinant viruses, and purified by sequential chromatography. This recombinant protein has a size of 20-21 kDa (glycoprotein).

SwissProt ID Link P05231
Gene Aliases IL6, IFNB2
Function Cytokine with a wide variety of biological functions. It is a potent inducer of the acute phase response. Plays an essential role in the final differentiation of B-cells into Ig-secreting cells Involved in lymphocyte and monocyte differentiation. Acts on B-cells, T-cells, hepatocytes, hematopoietic progenitor cells and cells of the CNS. Required for the generation of T(H)17 cells. Also acts as a myokine. It is discharged into the bloodstream after muscle contraction and acts to increase the breakdown of fats and to improve insulin resistance. It induces myeloma and plasmacytoma growth and induces nerve cells differentiation
Subcellular Location Secreted
Involvement in Disease Disease susceptibility is associated with variations affecting the gene represented in this entry.

Disease description: An inflammatory articular disorder with systemic-onset beginning before the age of 16. It represents a subgroup of juvenile arthritis associated with severe extraarticular features and occasionally fatal complications. During active phases of the disorder, patients display a typical daily spiking fever, an evanescent macular rash, lymphadenopathy, hepatosplenomegaly, serositis, myalgia and arthritis.
Post-Translational Modification N- and O-glycosylated
Sequence Similarities Belongs to the IL-6 superfamily
