Mouse Decorin, DCN ELI

Decorin is a protein that in humans is encoded by the DCN gene.

Decorin is a proteoglycan that is on average 90 - 140 kilodaltons (kDa) in molecular weight.

It belongs to the small leucine-rich proteoglycan (SLRP) family and consists of a protein core containing leucine repeats with a glycosaminoglycan (GAG) chain consisting of either chondroitin sulfate (CS) or dermatan sulfate (DS).

Decorin is a small cellular or pericellular matrix proteoglycan and is closely related in structure to biglycan protein.

Decorin and biglycan are thought to be the result of a gene duplication.

This protein is a component of connective tissue, binds to type I collagen fibrils, and plays a role in matrix assembly.
