The Neurokinin 3 receptor is a part of a larger family of G-protein coupled receptors that binds all tachykinin proteins. (wikipedia.org)
While neurokinin B has the ability to bind to other Neurokinin receptors, the highest affinity lies in that of the NK3R receptor group. (wikipedia.org)
Neurokinin B has also been found to co-localize certain gonadal steroid hormone receptors. (wikipedia.org)
The kisspeptin, neurokinin B, and dynorphin cell groups are found to be co-localized to more than 95% of all of the aforementioned receptors in the arcuate nucleus. (wikipedia.org)
The responses to neurokinin A were also unaffected suggesting that neurokinin A did not mediate its effects via NK‐2 receptors. (mcmaster.ca)
These data suggest that neurokinin A, like substance P may be acting via NK‐1, rather than NK‐2 receptors, to produce excitation of wide dynamic range neurons in the dorsal horn of the cat spinal cord. (mcmaster.ca)

A subset of these receptors plays an important role in pain, including the neurokinin-1 (NK1) receptor, which is activated by a pain-transmitting neuropeptide called substance P. (sciencemission.com)
Although we focused on the neurokinin-1 receptor, our findings are likely applicable to many G-protein coupled receptors because many of them show sustained signaling within cells, and therefore require drugs that can enter cells and block the receptors in endosomes," said the senior author. (sciencemission.com)
Evidence suggests that substance P and activation of neurokinin-1 (NK-1) receptors in the RVM are involved in descending facilitation of nociception. (umn.edu)

Neurons9
Neurokinin B (NKB) neurons in the arcuate nucleus of the hypothalamus are considered to play an essential role in generating the pulsatile mode of GnRH/luteinizing hormone (LH) secretion. (bioone.org)
The aim of the present study was to investigate the effects of the non‐peptide NK‐2 receptor antagonist, SR 48968 on the responses of dorsal horn neurons to iontophoretic application of the endogenous NK‐2 receptor ligand, neurokinin A, and on synaptically elicited responses in chloralose‐anaesthetized cats. (mcmaster.ca)
The effect of iontophoretic application of neurokinin A was tested on 51 dorsal horn neurons. (mcmaster.ca)
Neurokinin A induced a slow, prolonged excitation of 25 of the wide dynamic range neurons. (mcmaster.ca)
SR 48968 (50 pg to 1.0 mg/kg, i.v.) did not affect the on‐going basal activity ( n = 8) or the slow excitation induced by neurokinin A in any of the nine wide dynamic range neurons tested. (mcmaster.ca)
To eliminate the possibility that systemically administered SR 48968 may not be reaching central sites, SR 48968 was also applied iontophoretically (70-120 nA) to five neurons and tested against excitatory responses to iontophoretically applied neurokinin A. The on‐going activity of these cells were unaffected by SR 48968. (mcmaster.ca)
However, responses of wide dynamic range neurons to neurokinin A were totally blocked by i.v. administration (0.5 mg/kg) of the NK‐1 receptor antagonists CP‐96,345 ( n = 7) and CP‐99,994 ( n = 5) but not by CP‐96,344 ( n = 4), the inactive enantiomer of CP‐96,345. (mcmaster.ca)
Neurokinin A (NKA) was observed in a population of C-fibres and small neurons where it could co-localize with SP. (lu.se)

(ulaval.ca)
Curiously, inhibition of neurokinin receptor 1 (NK1R) failed to alleviate acute migraine attacks in clinical trials, and the neurokinins were consequently abandoned as potential antimigraine candidates. (lu.se)
Among them, neuropeptide substance P (SP) and its related receptor neurokinin-1 receptor (NK1R) have attracted unprecedented attention in tumorigenesis processes. (bvsalud.org)

The retention time of tumor neurokinin B on reversed-phase HPLC was the same as that of synthetic neurokinin B. Peptides with the retention times of substance P, neurokinin A, neurokinin A(3-10)-peptide and neuropeptide K were also identified in the tumor extract. (uaeu.ac.ae)

Five exon segments in the TAC3 gene encode for the NKB precursor known as preprotachykinin B. Preprotachykinin B is then proteolytically cleaved into the pro-peptide proneurokinin B.
