Background
Decorin, also known as PG40 and PGS2, is a secreted chondroitin/dermatan sulfate proteoglycan belonging to the small leucine-rich proteoglycans (SLRPs) family which is characterized by N-terminal and C -terminal cysteine-rich regions which flank the 10 - 12 tandem leucine-rich repeats (LRR) central region. Decorin is an N-glycosylated protein that also carries a variably-sized hybrid chondroitin/dermatan sulfate chain at Ser34. Decorin is subjected to alternative splicing to generate various isoforms. Decorin is degradable in the extracellular space by LRP-mediated endocytosis. Mature human Decorin shares 80% and 78% amino acid sequence identity with mouse and rat Decorin, respectively. Decorin regulates assembly of the extracellular collagen matrix and the bioactivity of the matrix associated growth factors FGF-2, GDF-8/Myostatin, TGF-β, and WISP-1. It can also bind and activate EGF R, ErbB4, and IGF-I R. Decorin has shown multiple functions in promoting myoblast differentiation, supporting angiogenesis, and inhibiting tumor progression.
