Neuropeptide W/neuropeptide B receptors (version 2019.4) in the IUPHAR/BPS Guide to Pharmacology Database

Abstract


The neuropeptide BW receptor 1 (NPBW1, provisional nomenclature [5]) is activated by two 23-amino-acid peptides, neuropeptide W (neuropeptide W-23) and neuropeptide B (neuropeptide B-23) [20, 6]. C-terminally extended forms of the peptides (neuropeptide W-30 and neuropeptide B-29) also activate NPBW1 [2]. Unique to both forms of neuropeptide B is the N-terminal bromination of the first tryptophan residue, and it is from this post-translational modification that the nomenclature NPB is derived. These peptides were first identified from bovine hypothalamus and therefore are classed as neuropeptides. Endogenous variants of the peptides without the N-terminal bromination, des-Br-neuropeptide B-23 and des-Br-neuropeptide B-29, were not found to be major components of bovine hypothalamic tissue extracts. The NPBW2 receptor is activated by the short and C-terminal extended forms of neuropeptide W and neuropeptide B [2].
