Description
IL-6 is similar to other interleukins in that it has a compact globular folding structure and is held in place by two disulfide bonds. The cysteine involved in forming these two disulfide bonds is highly conserved. IL-6, expressed by a variety of cells, regulates cell growth and differentiation in various tissues and is an important pro-inflammatory and immunomodulatory cytokine.
