Neurokinin B belongs to the tachykinin family of peptides. Neurokinin B binds a family of GPCRs-including neurokinin receptor 1 (NK1R), NK2R, and NK3R-to mediate their biological effect[1].
Neurokinin B (NKB) belongs to the tachykinin family of peptides that initially included the neuropeptides substance P (SP), neurokinin A (NKA), and NKB and more recently, endokinins and hemokinins. Tachykinins bind a family of G-protein-coupled receptors (GPCRs)-including neurokinin receptor 1 (NK1R), NK2R, and NK3R-to mediate their biological effect[1].
