Rat 7 395 10q22 Nmur2 neuromedin U receptor 2 18
Structural Information Comments
For human NMU2, sequences encoding both 412 and 415 amino acids have been reported as a consequence of the presence of two potential translation initiation sites. It is unclear which form is expressed physiologically, although there is circumstantial evidence to favour the shorter form [4].
There is evidence for the existence of receptor haplotypes [3].

Agonist Comments
1) pIC50 for neuromedin S is determined against 50pM [125I-Tyr0]-neuromedin S
2) Agonism and pEC50 values are based on Ca2+ signaling by recombinant receptors expressed in cell lines.

Tissue Distribution
Peripherally: in testis and lung.
Centrally: in spinal cord, hippocampus, medulla oblongata, pontine reticular formation, thalamus and hypothalamus and cortex.
Also found to be overexpressed in pancreatic ductal adenocarcinoma and in metastatic tissues.
Species:  Human
Technique:  Northern blot, quantitative PCR, in situ hybridization
References:  18,24,37,41
A similar pattern to that of human:
Expression in medulla, spinal cord, hypothalamus, thalamus, midbrain, and pons. More specifically in the hypothalamus in the paraventricular nucleus (PVN), the wall of the third ventricle, arcuate nucleus in dispersed and punctuate manner, dorsal and lateral arcuate nucleus around the periphery of the ventromedial hypothalamus (VMH).
Species:  Mouse
Technique:  Northern blot, quantitative PCR, in situ hybridization
References:  9,11
A similar pattern to that of human:
Expression in hypothalamus, hippocampus and spinal cord. More specifically in the hypothalamus in the paraventricular nucleus (PVN), the wall of the third ventricle, the mediopostal region of the arcuate, and in the CA1 region of the hippocampus, medulla oblongata and striatum. Greatest expression in the uterus and ovary.
Species:  Rat
Technique:  Northern blot, in situ hybridization, quantitative PCR

Physiological Functions Comments
Evidence across species (human, rat, mouse) for involvement in a range of patho-physiological aspects including:
Inhibition of food intake and increase energy expenditure [2,11,15-16,18,20,22-23,25-26,31,33,35,47,50].
Stimulation of stress response and hypothalamic-pituitary-adrenal axis [14,18,21,34,43,45,47,51].
Regulation of reproductive system hormones [8,32,34,36,39,46,48].
Pro-nociceptive effect [6,30,44,49-50].
Inhibition of bone formation and remodeling [38,40].
Regulation of circadian rhythm [12,28-30].
Pancreatic cancer [24].
