Comparison
While Kisspeptin is a key regulator of the hypothalamic–pituitary–gonadal axis, controlling puberty and fertility; kisspeptin-10 also inhibits trophoblast invasion and tumor metastasis in experimental models339199, Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48.
While Kisspeptin works as a family of peptides (eg, kisspeptin-10, -13, -14, -54) derived from the KISS1 precursor that activate G-protein–coupled receptor KISS1R (GPR54), triggering GnRH release and regulating pubertal onset and reproductive axis activity339199, Matrixyl is a palmitoylated pentapeptide, Pal-Lys-Thr-Thr-Lys-Ser (Pal-KTTKS), that acts as a matrikine, signaling to dermal fibroblasts to increase production of collagen, elastin, fibronectin, and other ECM components4858.
Kisspeptin is 10 amino acids long, whereas Matrixyl is shorter as it has a length of 5 amino acids. Kisspeptin is made up of a sequence of Tyrosine, Asparagine, Tryptophan, Asparagine, Serine, Phenylalanine, Glycine, Leucine, Arginine, Tyrosine. Matrixyl is made up of a sequence of Lysine, Threonine, Threonine, Lysine, Serine.
