Abstract
Tachykinins (TKs) are a family of peptides which share the common C-terminal sequence Phe-Xaa-Gly-Leu-MetNH2. Three peptides of this family, substance P (SP), neurokinin A (NKA) and neurokinin B (NKB) (Table I), have an established role as neurotransmitters in mammals. SP and NKA are produced through the expression of the same gene, preprotachykinin I (PPT I) while the PPT II gene encodes NKB.23,24 Two N-terminally extended forms of NKA, neuropeptide K and neuropeptide γ are also produced from the PPT I gene, but their status of neurotransmitters is not yet firmly established.
