Its activity is inseparable from its copper cargo GHK is the delivery vehicle, Cu is much of the payload and together they act as a matrix-signaling molecule that rewires fibroblast behavior, angiogenesis, and gene expression toward a more youthful tissue profile

It binds to actin and promotes cell migration including the mobilisation, migration, and differentiation of stem/progenitor cells that form new blood vessels and regenerate tissue

However, the resulting cryo-EM map from this sample only showed low-resolution features, indicating the structural flexibility of this complex
