Function
While MGF is upregulated in muscle after mechanical overload, where it supports tissue repair and growth; recombinant forms are studied for regenerative and performance-enhancement effects22138, Semaglutide is approved for type 2 diabetes and chronic weight management, significantly lowering HbA1c and body weight by modulating incretin pathways232480.
Mechanism
While MGF works as a 24-amino-acid E-peptide splice variant of IGF-1 (IGF-1Ec) produced in mechanically stressed or damaged muscle that activates IGF1R and local anabolic pathways involved in muscle repair and hypertrophy22138144, Semaglutide is a modified GLP-1(7–37) analog with three key changes—Ala8→Aib, Lys26 acylated with a C18 fatty diacid, and Lys34→Arg—resulting in a long-acting GLP-1 receptor agonist that enhances glucose-dependent insulin secretion, suppresses glucagon, slows gastric emptying, and reduces appetite23647480.
Length and Sequence
MGF is 24 amino acids long, whereas Semaglutide is longer as it has a length of 31 amino acids. MGF is made up of a sequence of Tyrosine, Glutamine, Proline, Proline, Serine, Threonine, Asparagine, Lysine, Asparagine, Threonine, Lysine, Serine, Glutamine, Arginine, Arginine, Lysine, Glycine, Serine, Threonine, Phenylalanine, Glutamic acid, Glutamic acid, Arginine, Lysine. Semaglutide is made up of a sequence of sequence data not available in the current dataset.
