Melanotan Peptides
Melanocortin receptor agonists originally developed at the University of Arizona. These cyclic peptides activate MC1R through MC5R subtypes, making them valuable tools for investigating melanogenesis, photoprotection signaling, and the broader melanocortin system.

About Melanocortin Research
The melanocortin system comprises five receptor subtypes (MC1R through MC5R) distributed across diverse tissue types. MC1R, primarily expressed on melanocytes, mediates pigmentation signaling through the cAMP-MITF-tyrosinase cascade. Research into these pathways continues to reveal connections between melanocortin signaling and broader physiological processes including appetite regulation (MC4R), immune modulation (MC3R), and exocrine gland function (MC5R).
