Abstract

Leptin, a hormone secreted by adipocytes, is made up of 146 amino acids. Human leptin has an 83% homology with rat leptin and 84% with mouse leptin. The gene that encodes for this protein is the Ob gene and is located on human chromosome 7q31.3. This gene consists of 650 kb and is made up of 3 exons separated by 2 introns. In rats, it is located on chromosome 5q33 (the region that codes for the synthesis of leptin is located in exons 2 and 3). The promoter region of the gene is regulated by various elements such as cyclic AMP and glucocorticoids, although the regions responsible for specific expression in adipose tissue or energy balance are still unknown
