Skin care by Keratins

Article Abstract:

Keratin proteins perform several functions in skin cells by providing mechanical support and protection against injury. Recent studies implicate that keratin plays a more active role in the regulation of protein synthesis and cell size, thus highlighting an overlooked non-mechanical function for skin keratins in healing wounds.
