Neurokinins (Tachykinins) — frequently asked

What are neurokinins?
Neurokinins are members of the tachykinin peptide family, defined by a conserved C-terminal Phe-X-Gly-Leu-Met amide motif. Neurokinin A and neurokinin B are the main representatives, and both are described as acting through the NK1, NK2 and NK3 receptor subtypes.
How do neurokinin A and neurokinin B differ?
They come from different genes and differ in sequence outside the shared C-terminal motif. Neurokinin A is generally reported as preferring the NK2 receptor and neurokinin B the NK3 receptor, though selectivity is relative and overlapping activity is common.
Why are so many truncated analogues listed?
Peptides such as [Nle10]-neurokinin A (4-10) are structure-activity tools. Shortening the sequence and substituting individual residues lets researchers test which parts of the peptide drive receptor preference and how modifications affect resistance to enzymatic degradation.
