Function

This gene belongs to a family of genes that function as receptors for tachykinins. Receptor affinities are specified by variations in the 5'-end of the sequence. The receptors belonging to this family are characterized by interactions with G proteins and 7 hydrophobic transmembrane regions. This gene encodes the receptor for the tachykinin neurokinin 3, also referred to as neurokinin B.[6]

Selective ligands

A number of selective ligands are available for NK3. NK3 receptor antagonists are being investigated as treatments for various indications.[7]

Agonists

  • Neurokinin B – endogenous peptide ligand, also interacts with other neurokinin receptors but has highest affinity for NK3
  • Senktide – 7-amino acid polypeptide, NK3 selective, CAS# 106128-89-6

Antagonists

  • Fezolinetant (ESN-364)
  • Osanetant (SR-142,801)
  • Pavinetant (MLE-4901, AZD-4901, AZD-2624)
  • Talnetant (SB-223,412)
  • SB-222,200 – potent and selective antagonist, Ki = 4.4 nM, 3-Methyl-2-phenyl-N-[(1S)-1-phenylpropyl]-4-quinolinecarboxamide, CAS# 174635-69-9
  • SB-218,795 – more selective than SB-222,200, Ki = 13 nM, (R)-[(2-Phenyl-4-quinolinylcarbonyl)amino]-methyl ester benzeneacetic acid, CAS# 174635-53-1
