WebCytokines exist in broad families that are structurally related but may contain rather diverse cytokine functions. Families of cytokines share sequence similarity and exhibit … WebCytokines of the IL6/GCSF/MGF family are glycoproteins of about 170 to 180 amino acid residues that contain four conserved cysteine residues involved in two disulphide bonds. [22] They have a compact, globular fold (similar to other interleukins), stabilised by the two disulphide bonds.
