Summary
Kisspeptin-10 is a decapeptide fragment of the larger kisspeptin protein. It is the minimal bioactive sequence at the kisspeptin receptor (KISS1R / GPR54) and is studied in literature on the hypothalamic-pituitary-gonadal (HPG) axis.
Overview
The kisspeptin family was identified in the early 2000s as a master upstream regulator of GnRH-releasing neurons. Kisspeptin-10 reproduces the C-terminal bioactive fragment of the parent peptide and is the standard reference compound in kisspeptin-pharmacology literature.
Research Background
Kisspeptin (originally named “metastin”) was identified by de Roux, Seminara, and colleagues in 2003 when loss-of-function mutations in the KISS1R gene were linked to hypogonadotropic hypogonadism. This established the kisspeptin/KISS1R system as the upstream regulator of GnRH neurons and the HPG axis.
Mechanisms Studied
Mechanistic interest centers on agonist activity at KISS1R, the downstream signaling that activates GnRH-releasing neurons in the hypothalamus, and the relationship between kisspeptin signaling and the broader regulation of the reproductive axis through GnRH release.
Published Research Summary
de Roux et al. (2003) and Seminara et al. (2003) describe the original identification of kisspeptin/KISS1R as the upstream regulator of the HPG axis. Pinilla et al. (2012) review the broader kisspeptin literature and its role in reproductive endocrinology.
Quality & Verification
For research compounds, lot-level documentation is the starting point for any analytical work. Researchers commonly examine batch-specific Certificates of Analysis, reversed-phase HPLC purity readouts, mass-spectrometry confirmation of molecular weight, and lot identification to evaluate compound identity, purity, and consistency before downstream experiments.
