ACTH secretion by mouse corticotroph AtT20 cells is negatively modulated by the intracellular level of 7B2.

Abstract

7B2 is a pan-neuroendocrine protein known to facilitate the trafficking and activation of the prohormone proprotein convertase-2 (PC2). 7B2-null mice not only lack PC2 activity, but they also develop an adrenocorticotropic hormone (ACTH) hypersecretion syndrome, suggesting that 7B2 may regulate hormone secretion. To verify this possibility, we introduced… (More)
