Genway ID:
GWB-393FE2
Immunogen:
3rd cytoplasmic domain of human. Synthetic peptide - KLH conjugated.
Uses: IHC (Optimal dilution to be determined by the researcher)
Function:
Receptor for metastin (kisspeptin-54 or kp-54) a C-terminally amidated peptide of KiSS1. KiSS1 is a metastasis suppressor protein that suppresses metastases in malignant melanomas and in some breast carcinomas without affecting tumorigenicity. The metastasis suppressor properties may be mediated in part by cell cycle arrest and induction of apoptosis in malignant cells. The receptor is essential for normal gonadotropin-released hormone physiology and for puberty. The hypothalamic KiSS1/KISS1R system is a pivotal factor in central regulation of the gonadotropic axis at puberty and in adulthood. The receptor is also probably involved in the regulation and fine-tuning of trophoblast invasion generated by the trophoblast itself. Analysis of the transduction pathways activated by the receptor identifies coupling to phospholipase C and intracellular calcium release through pertussis toxin-insensitive G(q) proteins.
Subcellular Location:
Membrane; multi-pass membrane protein.
Tissue Specificity:
Most highly expressed in the pancreas placenta and spinal cord with lower-level of expression in peripheral blood leukocytes kidney lung fetal liver stomach small intestine testes spleen thymus adrenal glands and lymph nodes. In the adult brain expressed in the superior frontal gyrus putamen caudate nucleus cingulate gyrus nucleus accumbens hippocampus pons and amygdala as well as the hypothalamus and pituitary. Expression levels are higher in early (7-9 weeks) than term placentas. Expression levels were increased in both early placentas and molar pregnancies and were reduced in choriocarcinoma cells. Expressed at higher levels in first trimester trophoblasts than at term of gestation. Also found in the extravillous trophoblast suggesting endocrine/paracrine activation mechanism.
Induction:
Expressed at higher levels in first trimester trophoblasts than at term of gestation.
Disease:
Defects in KISS1R are a cause of isolated hypogonadotropic hypogonadism (IHH) [MIM:146110]. Hypogonadotropic hypogonadism is defined as a deficiency of the pituitary secretion of follicle-stimulating hormone and luteinizing hormone which results in the impairment of pubertal maturation and of reproductive function. In the absence of pituitary or hypothalamic anatomical lesions and of anosmia (Kallmann syndrome) hypogonadotropic hypogonadism is referred to as isolated hypogonadotropic hypogonadism (IHH).
Similarity:
Belongs to the G-protein coupled receptor 1 family [view classification]. Summary: The protein encoded by this gene is a galanin-like G protein-coupled receptor that binds metastin a peptide encoded by the metastasis suppressor gene KISS1. The tissue distribution of the expressed gene suggests that it is involved in the regulation of endocrine function and this is supported by the finding that this gene appears to play a role in the onset of puberty.
