Kisspeptin
A hypothalamic neuropeptide encoded by the KISS1 gene, studied as the upstream regulator of GnRH release and the reproductive endocrine axis.
⏱ Half-Life
Short duration profile
Kisspeptin demonstrates a short half-life characteristic in research literature, shaping how observation windows and study timelines are typically structured.
⚡ Onset Characteristics
Fast measurable response
Onset is observed as fast — a property that influences how researchers structure comparative studies versus other compounds in the signalling research category.
🧠 Key Notes
What makes it distinct
- 01Encoded by the KISS1 gene
- 02Primary upstream trigger of GnRH neurons
- 03Central to puberty onset and fertility research
🧬 Mechanism of Action
How it works
Kisspeptin binds the GPR54 (KISS1R) receptor on hypothalamic GnRH neurons, triggering pulsatile release of gonadotropin-releasing hormone. This in turn drives pituitary secretion of LH and FSH, which regulate gonadal steroidogenesis and gametogenesis. Kisspeptin sits at the apex of the hypothalamic-pituitary-gonadal (HPG) axis and integrates metabolic, circadian, and steroid-feedback signals into reproductive output. Loss-of-function KISS1R mutations cause hypogonadotropic hypogonadism, confirming kisspeptin's non-redundant role in reproductive activation.
