The melanocyte-stimulating hormones, known collectively as MSH, also known as melanotropins or intermedins, are a family of peptide hormones and neuropeptides consisting of α-melanocyte-stimulating hormone (α-MSH), β-melanocyte-stimulating hormone (β-MSH), and γ-melanocyte-stimulating hormone (γ-MSH) that are produced by cells in the pars intermedia of the anterior lobe of the pituitary ...
α-Melanocyte-stimulating hormone (α-MSH) is an endogenous peptide hormone and neuropeptide of the melanocortin family, with a tridecapeptide structure and the amino acid sequence Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH 2.
Its main functions are in melanogenesis and anti-inflammatory signaling. [9] MC2R is expressed in the adrenal cortex and adipocytes and promotes steroidogenesis. [10] MC3R and MC4R are primarily expressed in the brain and regulate energy homeostasis. [1] MC3R is additionally involved in immunomodulation while MC4R has a role in sexual function.
It is a melanocortin, specifically, one of the three types of melanocyte-stimulating hormone (MSH), and is produced from proopiomelanocortin (POMC). [1] It is an agonist of the MC 1, MC 3, MC 4, and MC 5 receptors. [1] β-MSH is also known to decrease food intake in animals such as rats, chicken due to the effect of proopiomelanocortin (POMC). [2]
γ-Melanocyte-stimulating hormone (γ-MSH) is an endogenous peptide hormone and neuropeptide. [1] It is a melanocortin, specifically, one of the three types of melanocyte-stimulating hormone (MSH), and is produced from proopiomelanocortin (POMC). [1] It is an agonist of the MC 1, MC 3, MC 4, and MC 5 receptors. [1]
The melanocortin 1 receptor (MC1R), also known as melanocyte-stimulating hormone receptor (MSHR), melanin-activating peptide receptor, or melanotropin receptor, is a G protein–coupled receptor that binds to a class of pituitary peptide hormones known as the melanocortins, which include adrenocorticotropic hormone (ACTH) and the different forms of melanocyte-stimulating hormone (MSH).
As for the orgasm connection, oxytocin is produced in the hypothalamus (i.e., the control center of the brain), which is yet another region activated—both in the posterior and anterior—during ...
This is mainly a consequence of alpha-MSH being secreted along with the hormone associated with reproductive tendencies in primates. Alpha-MSH is a cleavage product of ACTH that has an equal affinity for the MC1 receptor on melanocytes as ACTH. [25] Melanosomes are vesicles that package the chemical inside a plasma membrane.
