Pomc processing enzymes
WebThe mechanism underlying the leptin-induced increased sympathetic nerve activity and cardiovascular tone was investigated in normal rats. The melanocortin (MC) peptides and other fragments derived from proopiomelancortin (POMC) have a diverse array of biological activities and have been implicated in mediating the feeding behavioral responses to leptin. WebMay 1, 2016 · Hence, the processing enzymes that include various endoproteases and exopeptidases involved in the maturation of POMC have to function within this pH range. The first step in POMC processing is endoproteolytic cleavage at signature pairs of basic residues . The major endoproteolytic enzymes for these cleavages are PC1/3 and PC2.

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 extensive, tissue-specific, post-translational processing via cleavage by subtilisin-like enzymes known as prohormone convertases. The encoded protein is synthesized mainly in corticotroph cells of the anterior pituitary, where four cle…
