Kisspeptin

Product research information

Kisspeptin-10 possesses the molecular formula C₆₃H₇₈N₁₈O₁₄ and consists of a chain of 10 amino acids. It is derived from the KISS1 gene, which encodes a larger precursor protein known as metastin. This specific fragment is chemically synthesized to retain the bioactive carboxyl-terminal sequence required for receptor binding affinity in laboratory settings.

The primary mechanism of action explored in scientific literature involves the binding of Kisspeptin-10 to the GPR54 receptor. Upon activation, this receptor initiates intracellular signaling cascades involving phospholipase C and calcium mobilization. Studies suggest that this signaling pathway is critical for the depolarization of GnRH neurons, thereby influencing the pulsatile secretion of downstream hormones such as Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH).

In animal models, Kisspeptin-10 is frequently utilized to study the onset of puberty and the regulation of reproductive feedback loops. Research indicates that the peptide may play a pivotal role in metabolic status and reproductive function connection. Investigators also examine the sensitivity of the GPR54 receptor to desensitization following continuous exposure to the ligand in vitro.
