ID:PGS1_HUMAN DESCRIPTION: RecName: Full=Biglycan; AltName: Full=Bone/cartilage proteoglycan I; AltName: Full=PG-S1; Flags: Precursor; FUNCTION: May be involved in collagen fiber assembly (By similarity). SUBUNIT: Homodimer. Forms a ternary complex with MFAP2 and ELN (By similarity). SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular matrix (By similarity). TISSUE SPECIFICITY: Found in several connective tissues, especially in articular cartilages. PTM: The two attached glycosaminoglycan chains can be either chondroitin sulfate or dermatan sulfate (By similarity). SIMILARITY: Belongs to the small leucine-rich proteoglycan (SLRP) family. SLRP class I subfamily. SIMILARITY: Contains 12 LRR (leucine-rich) repeats.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

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.
