Decorin is a small leucine-rich proteoglycan (SLRP) that plays a significant role in the extracellular matrix (ECM) of various tissues. It is composed of a core protein and one or more glycosaminoglycan chains, typically dermatan sulfate or chondroitin sulfate. Decorin is widely recognized for its ability to interact with collagen fibers, thereby influencing the structural integrity and mechanical properties of the ECM.
