NPBWR1 Membrane Protein Introduction

Introduction of NPBWR1

Encoded by NPBWR1 gene which is located on chromosome 10q11.2-121.1 in human, neuropeptide B/W receptor-1 (NPBWR1) has been known as orphan receptor GPR7. In human and rodents, the NPBWR1 gene is mainly localized within the central nervous system (CNS), including the hippocampus, hypothalamus, subcortical limbic telencephalon, olfactory cortex, and tegmental area, suggesting that the NPBWR1 receptor is involved in cardiovascular and neuroendocrine responses, homeostasis regulation, reward system, as well as locomotor activity.

Function of NPBWR1 Membrane Protein

Neuropeptide B (NPB) and neuropeptide W (NPW) are two endogenous peptide ligands of NPBWR1 which were identified in 2003. Due to the pharmacological effects of NPB and NPW, NPBWR1 has been served as a potential new therapeutic target. In recent years, a series of researches have suggested NPBWR1 to be involved in neuroendocrine function, energy homeostasis, feeding behavior, and modulating inflammatory pain. In addition, NPBWR1 is a novel anti-obesity target, and scientists are trying to develop an antagonist as the pharmacological tool. The neuropathic pain induced by acute inflammatory and trauma increases the myelin-associated expression of NPBWR1, suggesting its powerful role in analgesia. Moreover, the seizure activity reduced by the administration of NPW in the brain, suggesting that NPWR1 might be the potential target for epilepsy.
