WebMar 2, 2024 · Alpha-Melanocyte Stimulating Hormone (a-MSH) is a subcategory of MSH (there’s also beta and gamma MSH). The two most prominent roles that a-MSH has in … Acting through melanocortin 1 receptor, α-MSH stimulates the production and release of melanin (a process referred to as melanogenesis) by melanocytes in skin and hair. Acting in the hypothalamus, α-MSH suppresses appetite. α-MSH secreted in the hypothalamus also contributes to sexual arousal. In some animals (such as the claw-toed frog Xenopus laevis) production of MSH is increased wh…
