General Information
Term glycosaminoglycan-protein linkage region biosynthetic process ID (Ontology) GO:0120532 (Gene Ontology)
Definition The formation of a tetrasaccharide linker sequence (xylose-galactose-galactose-glucuronate) on specific serine residues of a core protein, on to which dermatan sulfate, chondroitin sulfate, heparan sulfate or heparin glycosaminoglycans may be assembled to synthesise the corresponding proteoglycan.
Also Known As "Glycosaminoglycan biosynthesis, linkage tetrasaccharide" ; "glycosaminoglycan-protein linkage region biosynthesis"
