1. What is Kisspeptin-10? (Identity & Definition)

Kisspeptin-10 (KP-10) is a synthetic decapeptide fragment derived from the C-terminal active region of the endogenous Kisspeptin family of peptides encoded by the KISS1 gene.

As a biologically active fragment of Kisspeptin-54, Kisspeptin-10 retains high affinity for the Kisspeptin receptor (KISS1R, also known as GPR54) and is widely used in research investigating neuroendocrine signaling pathways, reproductive hormone regulation, and hypothalamic-pituitary-gonadal (HPG) axis mechanisms.

Kisspeptin signaling was initially identified through studies of metastasis suppression pathways and was later recognized as a critical regulatory system involved in reproductive neuroendocrinology.
