Proopiomelanocortin Deficiency Treated with a Melanocortin

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.
