| receptors, neurokinin-1 | A class of cell surface receptors for tachykinins with a preference for substance p. Neurokinin-1 (nk-1) receptors have been cloned and are members of the G-protein coupled receptor superfamily. They are found on many cell types including central and peripheral neurons, smooth muscle cells, acinar cells, endothelial cells, fibroblasts, and immune cells. (12 Dec 1998) |

| receptors, neurokinin-2 | A class of cell surface receptors for tachykinins that prefers neurokinin a (nka, substance k, neurokinin alpha, neuromedin l), neuropeptide k (npk), or neuropeptide gamma over other tachykinins. Neurokinin-2 (nk-2) receptors have been cloned and are similar to other g-protein coupled receptors. (12 Dec 1998) |
| receptors, neurokinin-3 | A class of cell surface receptors for tachykinins that prefers neurokinin b (neurokinin beta, neuromedin k) over other tachykinins. Neurokinin-3 (nk-3) receptors have been cloned and are members of the g-protein coupled receptor superfamily. They have been found in the central nervous system and in peripheral tissues.

| neurokinin a | <chemical> A mammalian decapeptide tachykinin found in the central nervous system. It is similar in structure and action to substance p and neurokinin k. The compound has bronchoconstrictor, smooth muscle constrictor, and hypotensive effects and also activates the micturition reflex. Chemical name: Kassinin, 1-de-L-aspartic acid-2-de-L-valine-3-L-histidine-5-L-threonine-7-L-serine- (12 Dec 1998) |
| neurokinin k | <chemical> A mammalian decapeptide tachykinin found in the central nervous system. It is similar in structure and action to substance p and substance k (neurokinin a). The compound has bronchoconstrictor, smooth muscle constrictor, and hypotensive effects and also activates the micturition reflex. Chemical name: Kassinin, 2-L-methionine-3-L-histidine-4-de-L-lysine-5-de-L-serine-7-L-phenylalanine- (12 Dec 1998) |
