Decorin is a leucine-rich proteoglycan commonly found amongst ECPs. Its role is to stabilize the organization
of collagen fibrils into longer, thicker cables, helping support the extracellular scaffold of the
epidermis. A horseshoe-shaped molecule, decorin binds two triple helix collagen fibrils and orients them
in a staggered manner to add to the growing collagen fiber and maintain tissue shape.
