Human Gene DCN (ENST00000425043.5) Description and Page Index
  Description: Homo sapiens decorin (DCN), transcript variant C, mRNA. (from RefSeq NM_133505)
RefSeq Summary (NM_133505): This gene encodes a member of the small leucine-rich proteoglycan family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature protein. This protein plays a role in collagen fibril assembly. Binding of this protein to multiple cell surface receptors mediates its role in tumor suppression, including a stimulatory effect on autophagy and inflammation and an inhibitory effect on angiogenesis and tumorigenesis. This gene and the related gene biglycan are thought to be the result of a gene duplication. Mutations in this gene are associated with congenital stromal corneal dystrophy in human patients.

DESCRIPTION: RecName: Full=Decorin; AltName: Full=Bone proteoglycan II; AltName: Full=PG-S2; AltName: Full=PG40; Flags: Precursor;
FUNCTION: May affect the rate of fibrils formation.
SUBUNIT: Binds to type I and type II collagen, fibronectin and TGF-beta. Forms a ternary complex with MFAP2 and ELN. Interacts with DPT (By similarity).
SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular matrix.
PTM: The attached glycosaminoglycan chain can be either chondroitin sulfate or dermatan sulfate depending upon the tissue of origin.
DISEASE: Defects in DCN are the cause of congenital stromal corneal dystrophy (CSCD) [MIM:610048]. Corneal dystrophies are inherited, bilateral, primary alterations of the cornea that are not associated with prior inflammation or secondary to systemic disease. Most show autosomal dominant inheritance.
SIMILARITY: Belongs to the small leucine-rich proteoglycan (SLRP) family. SLRP class I subfamily.
SIMILARITY: Contains 12 LRR (leucine-rich) repeats.

ModBase Predicted Comparative 3D Structure on P07585
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
