Receptors7
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)
Additional NK3R receptors have also been found in various other places in the body including: uterus, mesenteric vein, gut neurons, and placenta. (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)
Neurokinin 3 receptor (NK3R) is the most selective of the tachykinin receptors, with highly preferential binding and activation by its endogenous ligand NKB (TAC3). (immune-system-research.com)
It binds to tachykinin receptors [neurokinin-1 receptor (NK1R), NK2R, NK3R] that belong, like most neuropeptide receptors, to the family of seven-transmembrane, G protein-coupled receptors. (niepokorny.org)
Neurons1
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)
TACR34
Much like the neurokinin B peptide, the NK3R receptor that it binds to is encoded within five exons of the TACR3 gene in humans and the Tacr3 gene in mice and other rodents. (wikipedia.org)
In vivo studies have shown that increased neurokinin B (NKB) / neurokinin 3 receptor (NK3R) signalling contributes to VMS, with previous genetic studies implicating the TACR3 gene locus that encodes NK3R. (biomedcentral.com)
Conditional analyses demonstrated independence of genetic signals for puberty timing and VMS at the TACR3 locus, including a rare variant predicted to reduce functional NK3R levels that was associated with later menarche ( P = 5 × 10 -9 ) but showed no association with VMS ( P = 0.6). (biomedcentral.com)
We provide support for TACR3 in the genetic basis of VMS but unexpectedly find that rare genomic variants predicted to lower NK3R levels did not modify VMS, despite the proven efficacy of NK3R antagonists. (biomedcentral.com)
Binds1
Neurokinin B binds to the receptor to stimulate its effects. (makeamedic.org)
Selective1
The present study aimed to clarify the role of NKB-neurokinin 3 receptor (NK3R) signaling in the pulsatile pattern of GnRH/gonadotropin secretion in postpartum lactating cattle.We examined the effects of the administration of an NK3R-selective agonist, senktide, on gonadotropin secretion in lactating cattle. (bioone.org)
Kisspeptin4
Reproductive function is highly dependent on levels of both neurokinin B and also the G-protein coupled receptor ligand kisspeptin. (wikipedia.org)
Neurokinin B is expressed along with the peptides kisspeptin and dynorphin A in the neuronal cells of the arcuate nucleus. (wikipedia.org)
A review of neurokinin B and its sister peptides, kisspeptin and dynorphin, in sheep found that these KNDy cell groups (kisspeptin, neurokinin B, dynorphin), are in direct contact with the GnRH neuronal bodies in both the preoptic area and the mediobasal hypothalamus. (wikipedia.org)
Due to the high percentage of co-localization found with neurokinin B cell bodies and receptor groups, it is suggested that Neurokinin B along with kisspeptin and dynorphin play a role in the release of GnRH. (wikipedia.org)
Senktide2
The NK3R receptor group when activated with a synthetic agonist of NKB, senktide, has been shown to stimulate the secretion of luteinizing hormone. (wikipedia.org)
The aim of this project was to investigate the effects of NK3R agonist senktide administration on neurobehavioral mechanisms in the experimental AD-like rat model. (bvsalud.org)
Neurokinin B (NKB), is encoded by the TAC3 gene in humans and Tac2 in rodent species. (wikipedia.org)
TAC31
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. A second proteolytic cleavage of proneurokinin B produces the final product neurokinin B. During the ovarian cycle, GnRH secretion along with that of luteinizing hormone (LH) is highly regulated. (wikipedia.org)
Oestrogen2
It has been shown that a deficiency of oestrogen increases neurokinin B overstimulating this pathway and therefore agents which antagonise the receptor could suppress the pathway and reduce vasomotor symptoms. (makeamedic.org)
I suspect there are 10-15 other pathways mediating low oestrogen causing flushing but the NKB/NK3R pathway appears to be the major efferent pathway that the others converge on to mediate menopausal flushing. (neuroendo.org.uk)
Flushes1
Recent research looking into the pathophysiology of hot flushes has identified a chemical pathway involving neurokinin B/neurokinin-3-receptor (NKB/NK3R) as being involved through interacting with areas in the brain which control body temperature and sensations. (makeamedic.org)
