Kisspeptin – KISS1R Research Peptide

Kisspeptin Research

Kisspeptin is a family of naturally occurring neuropeptides encoded by the KISS1 gene. Different kisspeptin forms, including kisspeptin-54, kisspeptin-14, kisspeptin-13, and kisspeptin-10, are generated from a common precursor and share a C-terminal RF-amide sequence. These peptides are studied extensively in reproductive neuroendocrinology and peptide signaling research.

Research Material for Laboratory Applications

Kisspeptin is intended for qualified laboratory and analytical research involving peptide biology, receptor pharmacology, neuroendocrine signaling, and reproductive biology.

Researchers can investigate kisspeptin under controlled experimental conditions to examine its molecular structure, receptor interactions, signaling activity, and relationship with the hypothalamic-pituitary-gonadal axis.

KISS1R Receptor Research

Kisspeptin exerts its biological activity primarily through the KISS1 receptor (KISS1R), previously known as GPR54. KISS1R is a G-protein-coupled receptor expressed in several tissues, with important expression in the hypothalamic regions involved in reproductive hormone regulation.

Activation of KISS1R can stimulate signaling in GnRH neurons. This makes the kisspeptin/KISS1R system an important model for studying communication between peptide signaling, the hypothalamus, pituitary gonadotropins, and reproductive physiology.

Kisspeptin and GnRH Research

A major area of kisspeptin research involves its relationship with gonadotropin-releasing hormone (GnRH). Experimental research has shown that kisspeptin signaling can stimulate GnRH neurons, providing an important connection between ki
