The neuropeptide BW receptor 1 (NPBW1) is activated by two 23-amino-acid peptides, neuropeptide W (NPW-23 (NPW, Q8N729)) and neuropeptide B (NPB-23 (NPB, Q8NG41)) [2,6]. C-terminally extended forms of the peptides (NPW-30 (NPW, Q8N729) and NPB-29 (NPB, Q8NG41)) also activate NPBW1 . Unique to both forms of NPB is the N-terminal bromination of the first tryptophan residue. des-Br-NPB-23 (NPB, Q8NG41) and des-Br-NPB-29 (NPB, Q8NG41) 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 NPB and NPW .
