Scyliorhinin I (Scy I) / Shark Substance P-Related Peptide is Discovered in shark species, these bioactive peptides exhibit antimicrobial and immunomodulatory properties. Scy I, a structurally unique peptide, plays a key role in shark innate immunity, while the Substance P-related peptide mirrors mammalian neuropeptide functions, highlighting evolutionary conservation in immune defense mechanisms. Both peptides hold promise for drug development and biomedical research.
