WebSep 7, 2024 · Different populations of POMC neurons are either inhibited or activated by insulin, which is regulated by the phosphatase TCPTP (T-cell protein tyrosine phosphatase), which is degraded after feeding and increases during fasting . Activation of IRs on a subset of POMC neurons on the other hand increases the firing of these neurons . WebThe POMC gene encodes for the POMC protein: 38. POMC is processed by the serine endoprotease, prohormone convertase 1/3 (PC1/3), encoded by the PCSK1 gene; POMC is proteolytically cleaved to form α-MSH, which activates MC4R downstream in the pathway
WebJun 1, 2024 · The melanocortin system refers to a set of hormonal and neuropeptidergic pathways that are comprised of three main components: pro-peptide proopiomelanocortin (POMC), which is post-translationally processed by prohormone convertases into a number of biologically active moieties, including α-melanocyte stimulating hormone (MSH), β … WebNational Center for Biotechnology Information
WebNov 3, 2024 · The central melanocortin system is a well-established neuronal pathway involved in regulating energy metabolism.
