Abstract
Natural silks are fibrous polymers built of several protein components. Commercial silk fibers are obtained from the cocoons of a handful of moth species by an ancient technology. The core proteins, which are responsible for filament formation in these silks, are called fibroins and the surface sticky proteins are sericins. Silk is still primarily used for textiles and related products but applications in cosmetics and medicine are of growing importance. Sericins have been commercialized as additives to tissue culture media and are being tested as scaffolds for tissue reconstruction. Modern transgenic technologies are used to obtain silk threads with new properties or to manufacture minor silk components. Controlled conversion of soluble proteins into filaments is the major problem in the development of recombinant silk fibers. Sericin-like recombinant proteins are promising for use in cosmetics, medicine, and industry.
