Background: Decorin

Decorin, also known as PG40 and PGS2, is a secreted chondroitin/dermatan sulfate proteoglycan in the family of small leucine‑rich proteoglycans (SLRPs). SLRP family members are characterized by N‑terminal and C‑terminal cysteine‑rich regions which flank the central region containing 10 ‑ 12 tandem leucine‑rich repeats (LRR) (1). The human Decorin cDNA encodes a 359 amino acid (aa) precursor that includes a 16 aa signal sequence and a 14 aa propeptide (2). Mature human Decorin contains twelve tandem LRR and shares 80% and 78% aa sequence identity with mouse and rat Decorin, respectively. Alternate splicing of human Decorin generates five isoforms with variable length deletions. Decorin is an N‑glycosylated protein that also carries a variably‑sized hybrid chondroitin/dermatan sulfate chain at Ser34 (3, 4). Naturally occurring Decorin proteoglycan has a molecular mass of approximately 100 kDa, and the deglycosylated Decorin core protein has a mass of approximately 40 kDa (5). Decorin regulates assembly of the extracellular collagen matrix and the bioactivity of the matrix associated growth factors FGF‑2, GDF‑8/Myostatin, TGF‑ beta, and WISP‑1 (4, 6 ‑ 9). It also binds and activates EGF R, ErbB4, and IGF‑I R (10 ‑ 12). In vivo, Decorin promotes myoblast differentiation, supports angiogenesis, and inhibits tumor progression (13 ‑ 16). Decorin is cleared from the extracellular space by LRP‑mediated endocytosis (17).
