There are three known mammalian tachykinin receptors termed NK1, NK2 and NK3. All are members of the 7 transmembrane G-protein coupled receptor family and induce the activation of phospholipase C, producing inositol triphosphate (so called Gq-coupled). Inhibitors of NK-1, known as NK-1 receptor antagonists, can be used as antiemetic agents, such as the drug aprepitant.

WebTachykinins are a family of neuropeptides that share the same hydrophobic C-terminal region with the amino acid sequence Phe -X- Gly - Leu - Met -NH 2, where X represents a hydrophobic residue that is either an aromatic or a beta-branched aliphatic. The N-terminal region varies between different tachykinins.

WebThe biological actions of tachykinins are brought about by three types of tachykinin receptor. Encoded by the genes TACR1, TACR2 and TACR3, they are currently named by the acronyms NK 1, NK 2 and NK 3. These receptors are coupled through G q and G 11 to phospholipase C.
