Collagen biosynthetic pathway

The collagen biosynthetic pathway encompasses transcription of collagen genes, translation of alpha-chain peptides, extensive post-translational modifications (hydroxylation, glycosylation), extracellular cleavage of propeptides, assembly into triple-helical structures, and formation of fibrils via cross-linking enzymes like lysyl oxidase. Its dysregulation leads to diverse connective tissue diseases, while specific molecular fragments from collagen can have potent bioactivities, such as antiangiogenic or antitumor roles. Because this is a broad synthesis pathway rather than a single molecular entity, it underpins key aspects of tissue structure, cell-matrix signaling, and disease but does not qualify as a classic therapeutic target like a receptor, enzyme, or transporter.
