Summary of "Neuropeptide PEN and its receptor GPR83; Distribution, Signaling and Regulation."

Neuropeptides are peptide neuromodulators that are expressed by neurons and act on neural targets by activating neuropeptide receptors1. These receptors serve as therapeutic targets for the treatment of a number of pathophysiological conditions, including obesity, pain and addiction2-6. Major technological advances in the 1980s involving improved sensitivity of peptide purification methods and single neuron mRNA sequencing techniques have led to an explosion in the number of newly discovered neuropeptides7. However, to date, receptors for many of these neuropeptides remain largely unknown. In addition, currently there are a number of "orphan" G-protein-coupled receptors (GPCRs) for which endogenous ligands or function are yet to be identified8, 9.These "orphan" neuropeptides and GPCRs represent an untapped resource for the development of therapeutics to treat chronic diseases including drug abuse disorders, obesity and neuropathic pain. With this in mind much effort has been put towards deorphanizing these "orphan" peptides/GPCRs. Here, we summarize current insights into one such relationship: that between the neuropeptide PEN and the GPCR named GPR83. This intriguing system promises to deepen our current understanding of neuropeptide/GPCR systems, but also highlights the necessity for further technological advances in order to fully understand its complexity.

Medical and Biotech [MESH] Definitions

A signal transducing tumor necrosis factor receptor associated factor that mediates signaling from CD27 ANTIGENS; CD40 ANTIGENS; and the LYMPHOTOXIN BETA RECEPTOR. It is involved in regulation of NF-KAPPA B signaling.

PKC beta encodes two proteins (PKCB1 and PKCBII) generated by alternative splicing of C-terminal exons. It is widely distributed with wide-ranging roles in processes such as B-cell receptor regulation, oxidative stress-induced apoptosis, androgen receptor-dependent transcriptional regulation, insulin signaling, and endothelial cell proliferation.

A signal transducing tumor necrosis factor receptor associated factor that is involved in regulation of NF-KAPPA B signaling and activation of MITOGEN-ACTIVATED PROTEIN KINASES.

A receptor for MACROPHAGE COLONY-STIMULATING FACTOR encoded by the c-fms proto-oncogene (GENES, FMS). It contains an intrinsic protein-tyrosine kinase activity. When activated the receptor undergoes autophosphorylation, phosphorylation of down-stream signaling molecules and rapid down-regulation.

A member of the tumor necrosis factor receptor superfamily that may play a role in the regulation of NF-KAPPA B and APOPTOSIS. It is found on activated T-LYMPHOCYTES; B-LYMPHOCYTES; NEUTROPHILS; EOSINOPHILS; MAST CELLS and NK CELLS. Overexpression of the Ki-1 antigen in hematopoietic malignancies make it clinically useful as a biological tumor marker. Signaling of the receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.
