Introduction to GHK-Cu Research
GHK-Cu (Glycyl-L-Histidyl-L-Lysine bound to copper) is a naturally occurring tripeptide studied in laboratory models for its role in cellular signaling, gene expression modulation, and extracellular matrix (ECM) communication. Copper binding enhances GHK’s role as a metallopeptide, facilitating controlled metal-mediated signaling pathways.
GHK-Cu research evaluations focus on how trace metal availability influences intracellular cascades and gene expression networks. As a carrier and signaling facilitator for copper ions, its structure allows selective metal ion transport and enzyme cofactor delivery in controlled laboratory settings.
