General Information
Term chondroitin sulfate proteoglycan biosynthetic process ID (Ontology) GO:0050650 (Gene Ontology)
Definition The chemical reactions and pathways resulting in the formation of chondroitin sulfate proteoglycans, which consist of a core protein linked to a chondroitin sulfate glycosaminoglycan. The chondroitin sulfate chain is composed of the repeating disaccharide unit beta-(1,4)-D-glucuronic acid-beta-(1,3)-N-acetyl-D-galactosamine, the latter of which can be O-sulfated. Chondroitin sulfate chains are covalently linked to serine/threonine residues (O-linked) of the core protein via a tetrasaccharide linker sequence (xylose-galactose-galactose-glucuronate).[ PubMed:17239763 ]
Also Known As "chondroitin sulfate proteoglycan anabolism" ; "chondroitin sulfate proteoglycan biosynthesis" ; "chondroitin sulfate proteoglycan formation" (for all, see Synonyms field below)
