Pro-opiomelanocortin (POMC) is a precursor polypeptide with 241 amino acid residues. POMC is synthesized in corticotrophs of the anterior pituitary from the 267-amino-acid-long polypeptide precursor pre-pro-opiomelanocortin (pre-POMC), by the removal of a 26-amino-acid-long signal peptide sequence during … See more POMC is cut (cleaved) to give rise to multiple peptide hormones. Each of these peptides is packaged in large dense-core vesicles that are released from the cells by exocytosis in response to appropriate stimulation: See more The levels of proopiomelanocortin (pomc) are regulated indirectly in some animals by the photoperiod. It is referred to the hours of light during a day and it changes across the seasons. Its … See more Mutations in this gene have been associated with early onset obesity, adrenal insufficiency, and red hair pigmentation. A study concluded … See more POMC is used as a target for a medication used to treat obesity in humans. The combination of bupropion and naltrexone acts via hypothalamic POMC neurons to decrease appetite. See more The POMC gene is located on chromosome 2p23.3. The POMC gene is expressed in both the anterior and intermediate lobes of the pituitary gland. This gene encodes a 285-amino acid polypeptide hormone precursor that undergoes … See more The large molecule of POMC is the source of several important biologically active substances .
