Q9NSA1

FGF21(Fibroblast growth factor 21) is a member of the fibroblast growth factor family. FGF21 plays a crucial role in metabolic regulation, particularly in glucose and lipid metabolism, making FGF21 an important target for research in metabolic disorders such as obesity and diabetes. FGF21 is primarily secreted by the liver and adipose tissue, and FGF21 expression is induced under conditions of stress, such as fasting or cold exposure. FGF21 acts on various tissues, including the liver, muscle, and adipose tissue, to promote energy expenditure and improve insulin sensitivity. Understanding FGF21 function and regulation is vital for developing therapeutic strategies aimed at treating metabolic diseases, as FGF21 has been shown to influence weight loss and improve metabolic health.
