Compound guide

KISSPEPTIN-10

A pathway-focused guide to molecular mechanisms, published evidence, and the limits of interpretation.

Overview

A Summary:KISSPEPTIN-10

Kisspeptin-10 is a short peptide form derived from the KISS1 precursor. Its receptor, KISS1R (also called GPR54), is studied in neuroendocrine signaling.

Receptor structures show peptide recognition and Gq coupling. Functional work follows calcium responses and signaling toward the hypothalamic–pituitary–gonadal axis.

The selected evidence combines receptor structures, engineered-cell assays and rat/explant studies. Species, sequence and analogue differences matter. These studies do not establish human clinical outcomes or verify the sequence or formulation of this catalog vial.

Research model

Cellular & MolecularHow KISSPEPTIN-10 Is Studied

These receptors, enzymes, and signaling networks define the primary laboratory questions associated with this research material.

01Peptide recognition and Gq coupling

KISS1R

At the cellular or molecular level

Cryo-EM structures describe KISS1R bound to kisspeptin-10 and a Gq protein complex. Ligand contacts and receptor shape help explain activation in the structural system.

02Functional structure–activity readout

Intracellular calcium

At the cellular or molecular level

A structure–activity study tested rat kisspeptin-10 analogues in receptor-expressing cells. Amino-acid substitutions altered calcium responses and activity in rats.

03Model-level hormone relay

GnRH / gonadotropin axis

At the cellular or molecular level

Rat and hypothalamic-explant experiments examined GnRH release and downstream LH/FSH responses. Pituitary-fragment experiments helped distinguish hypothalamic from direct pituitary effects.

Map the research pathway

From target to research question

Follow each target through its intracellular signal, the model being observed, and the evidence boundary that governs interpretation.

01

KISS1R

Peptide recognition and Gq coupling

Cryo-EM structures describe KISS1R bound to kisspeptin-10 and a Gq protein complex.

Peptide recognition and Gq coupling

Ligand–receptor contacts and active-complex geometry; a structure alone cannot predict a clinical response.

Interpret with limits

Pathway activity does not establish safety, efficacy, or suitability for personal use.

02

Intracellular calcium

Functional structure–activity readout

A structure–activity study tested rat kisspeptin-10 analogues in receptor-expressing cells.

Functional structure–activity readout

Calcium responses in transfected cells, NMR structure and rat LH responses; results are sequence- and species-specific.

Interpret with limits

Pathway activity does not establish safety, efficacy, or suitability for personal use.

03

GnRH / gonadotropin axis

Model-level hormone relay

Rat and hypothalamic-explant experiments examined GnRH release and downstream LH/FSH responses.

Model-level hormone relay

GnRH release in explants and gonadotropins in rats; these are not demonstrations of human fertility or catalog-vial efficacy.

Interpret with limits

Pathway activity does not establish safety, efficacy, or suitability for personal use.

Research interpretation

How to read the pathway.

01

Peptide recognition and Gq coupling

The structure shows how a peptide signal can engage its receptor.

02

Functional structure–activity readout

Changing a peptide’s sequence can change what the receptor does.

03

Model-level hormone relay

A downstream hormone measurement reflects a relay rather than a single receptor event.

Evidence boundary

The selected evidence combines receptor structures, engineered-cell assays and rat/explant studies. Species, sequence and analogue differences matter. These studies do not establish human clinical outcomes or verify the sequence or formulation of this catalog vial.
