Processing and sorting of pro-opiomelanocortin is an important checkpoint in regulating release of ACTH from secretory vesicles in pituitary cells

Warhurst A , Oliver RL , Davies RA , Pritchard LE , White A

Pro-opiomelanocortin (POMC) is endoproteolysed by prohormone convertase-1 (PC1) to ACTH within the secretory pathway in pituitary cells, where the regulation of ACTH release is essential for mediating the stress response. However POMC is present in the human circulation, indicating that not all POMC is processed. This suggests that regulation of trafficking and processing of POMC are important in determining ACTH release. To investigate this, we analysed steady-state release o...
