Tachykinin function
Websame molecules is the tachykinin family. Tachykinins (TKs) form a family of neuropeptides in vertebrates, represented by compounds such as Neurokinin A,26 Neurokinin B,27 hemo-kinin/endokinin K,28,29 and substance P (SP), which was the first TK discovered in alcoholic extracts of equine brain30 and then isolated from the bovine hypothalamus. WebSubstance P. Substance P (SP) is an 11 amino acid neuropeptide belonging to the tachykinin family. Three subtypes of neurokinin receptors (NK1, NK2, and NK3) mediate the biological actions of SP. The most abundant subtype in the CNS is NK1, which is present in the hippocampus, hypothalamus, and amygdala.

WebThe Tacr3 gene encodes tachykinin receptor 3 (NK3R), which belongs to the tachykinin receptor family. This family of proteins includes typical G protein-coupled receptors and belongs to the rhodopsin subfamily, and NK3R functions by binding to its high-affinity ligand, neurokinin B (NKB).
There are three known mammalian tachykinin receptors termed NK1, NK2 and NK3. All are members of the 7 transmembrane g protein-coupled family of receptors and induce the activation of phospholipase C, producing inositol triphosphate. NK1, NK2 and NK3 selectively bind to substance P, neurokinin A, and neurokinin B, respectively. Whilst the receptors are not specific to any individual tachykinin, they do have differing affinity for the tachykinins: 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 …
