Used in research and development of peptide-based therapeutics, particularly in studies related to neuropeptide function and enzyme substrate specificity. Commonly employed in the design of analogs for physiological peptides, aiding in the investigation of receptor binding and signal transduction mechanisms. Also utilized in protease assays due to the presence of proline-rich sequences that are substrates for specific peptidases. Its structure makes it suitable for studying collagen metabolism and connective tissue disorders. Frequently applied in pharmaceutical screening platforms for drug discovery targeting neurological and endocrine systems.
