Kisspeptin
PH-KISS-001
Specifications
Description
Kisspeptin is a family of neuropeptides encoded by the KISS1 gene that serve as critical regulators of reproductive function. These peptides activate the kisspeptin receptor (GPR54/KISS1R) to control gonadotropin-releasing hormone (GnRH) secretion.
Mechanism of Action
Kisspeptin directly stimulates GnRH neurons in the hypothalamus, triggering the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The kisspeptin system is essential for puberty onset and reproductive function, serving as a pivotal factor in the pubertal activation of the reproductive cascade (Kaiser & Kuohung, 2005). Kisspeptin expression in the brain acts as a catalyst for the initiation of puberty (Smith et al., 2007).
