JAG-1 (188-204)

This peptide is a fragment of the JAG-1 protein. JAG-1 is Notch ligand, a peptide that is the most conspiciously expressed ligand in skin. JAG-1 induces epidermal maturation. Exposing submerged keratinocytes monolayers to JAG-1 with elevated calcium concentration produces stratification with loricrin expression and NF-kB activation.
