PCSK2 (Proprotein Convertase Subtilisin/Kexin Type 2): PCSK2 is an enzyme involved in processing precursor proteins into their biologically active forms. It plays a key role in the maturation of neuropeptides and hormones within neuroendocrine tissues. Dysregulation of PCSK2 can impact the synthesis of important signaling molecules, affecting processes such as stress response, metabolism, and growth.
