Kisspeptin-10 is the minimal biologically active sequence derived from the cleavage of preprokisspeptin (encoded by the KISS1 metastasis-suppressor gene). Discovered to be central to reproductive endocrinology, kisspeptin neurons in the hypothalamus synapse directly onto GnRH neurons, serving as the master regulatory switch for luteinizing hormone (LH) and follicle-stimulating hormone (FSH) pulsatility.
