    basic FUNCTION
  • regulation of cancer metastasis in malignant melanomas
  • regulating events downstream of cell-matrix adhesion, perhaps involving cytoskeletal reorganization
  • directly stimulating gonadotrophin-releasing hormone release via KISS1R, and as a relevant downstream element in the neuroendocrine network governing LH secretion
  • activates a receptor coupled to Galphaq subunits, KISS1R (activation of KISS1R signaling may negatively regulate the role of CXCR4 in programming tumor metastasis)
  • strong suppressant of metastasis
  • having a potential autocrine metastasis suppression effect on KISS1R-positive tumor cells
  • being pivotal regulator of the hypothalamic-pituitary-gonadal axis and reproduction, with the ability to integrate signals from both internal and external sources
  • functional kisspeptin is important for puberty and reproduction in humans
  • is a key locus of integration for circadian and steroidal signaling necessary for the initiation of ovulation
  • KISS1, KISS1R play a major role in trophoblast invasion, and progesterone-induced blocking factor (PIBF1) is needed for maintaining pregnancy
  • may function in decidualized endometrium to prepare for adequate placentation but this autocrine secretion of KISS1 is deregulated during oncogenesis to enable tumor cells to spread
  • KISS1/KISS1R signaling is critical for regulating the activity of gonadotropin-releasing hormone (GNRH1) neurons in mammals
  • is a crucial activator of reproductive function
  • is a 'master regulator' of reproductive physiology, integrating limbic circuits with the regulation of gonadotropin-releasing hormone neurons and reproductive hormone secretion
  • plays an important role in regulating very early pregnancy events such as embryo implantation
  • KISS1 is a metastasis suppressor gene of pancreatic cancer, and this suppression is not dependent on the expression levels of KISS1R
  • CD82 and KISS1 are implicated in the pathogenesis and maintenance of endometriosis
  • KISS1 has a role in male sexual behavior, which is specific to the medial amygdala (MePD)
  • potential involvement of KISS1 protein in the pathogenesis and maintenance of adenomyosis
  • regulates osteosarcoma apoptosis and autophagy processes
    Signaling between KISS1/KISS1R is now recognized as being essential for normal fertility
    a component kisspeptin/KISS1R system appears to play an important role in the regulation of reproduction
    small molecule
  • metastin, ligand for KISS1R (AXOR12)(KISS1/KISS1R signalling may suppress the invasive phenotype of epithelial ovarian cancer)
  • MED23 is a key regulator in KISS1 transactivation in normal tissue, and the loss of MED23 expression, provokes increased tumor metastasis
  • cleaved by matrix metalloproteinases
  • associated with its receptor GPR54
  • binds directly to the kisspeptin (KISS1) promoter and stimulates KISS1 transcription
  • FURIN appears to be the essential enzyme for the generation of kisspeptin (KISS1)
  • interaction of KISS1 with KISS1R suppresses metastasis and also regulates release of gonadotropin-releasing hormone, which promotes secretion of estradiol (E2) and progesterone (P4)
  • regulates reproduction by stimulating GNRH1 secretion
  • cell & other
    Other intraovarian KISS1 is likely regulated by sympathetic nerves via a beta-adrenergic receptor and participates locally in ovarian follicular development in reproductive aging

    Therapy target
    target for antimetastatic therapeutic (antimetastatic agent in combination with MMP inhibitor)
    soluble KISS1, kisspeptins, or mimetics could be used to maintain tumor dormancy, rendering treatment of already disseminated tumor cells (i.e., micrometastases) a legitimate target
    KISS1 is potentially a novel target for gene therapy
