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).


The genes and receptor ligands are as follows:[1]

Receptor Gene Preferred ligand
NK1 TACR1 substance P
NK2 TACR2 neurokinin A
NK3 TACR3 neurokinin B
