Proteoglycans synthesis

Proteoglycans synthesis refers to a multistep biological process in which specific enzymes assemble core proteins and glycosaminoglycan (GAG) chains to generate proteoglycans—heterogeneous macromolecules that are major structural and functional components of the animal extracellular matrix. Synthesized in the endoplasmic reticulum and Golgi apparatus, their production involves sequential action by glycosyltransferases and sulfotransferases. Proteoglycans play crucial roles in tissue structure, hydration, cell adhesion, mechanosignaling, and regulation of growth factor bioavailability. Dysregulated proteoglycan synthesis or degradation is implicated in cancer, cardiovascular disease, connective tissue disorders such as Ehlers–Danlos syndrome, and inherited lysosomal storage disorders (mucopolysaccharidoses).
