Product Description
Kisspeptin-10 is a synthetic decapeptide corresponding to the conserved C-terminal fragment of the KISS1 gene product. The listed 145-amino-acid precursor gives rise to KP-54, KP-14, KP-13, and KP-10, which share the RF-amide terminus. KP-10 provides a defined molecular material for in-vitro KISS1R receptor and signaling assays.
KISS1R (GPR54) is described as a class A GPCR with Gq/11-associated signaling. The listed KISS1 gene locus is chromosome 1q32.1 and the receptor locus is chromosome 19p13.3. C-terminal amidation, salt form, and net peptide content are relevant identity parameters for interpretation of laboratory measurements.
Research Mechanisms and Laboratory Applications
KISS1R Binding and Gq Signaling
Assay contexts include phospholipase C (PLC), IP3/DAG signaling, intracellular Ca²⁺ measurements, PKC activation, ERK1/2 phosphorylation, and β-arrestin recruitment. The existing binding description lists Ki approximately 2.33 nM for human KISS1R and EC50 approximately 1.0 nM in a CHO-GPR54 IP accumulation assay (PMC5790198). Interpret these values according to the specific assay conditions.
Research endpoints include IP1 accumulation by HTRF, fluorometric calcium measurements, receptor binding, and phosphorylation panels. PDB 8XGS provides structural research context for docking and molecular-contact analysis.
Neuroendocrine Pathway Measurements
Laboratory research contexts include GnRH-associated signaling, LH/FSH secretion kinetics in ex-vivo systems, and steroidogenesis markers in cell cultures. CHO and HEK293 receptor-expression systems provide additional contexts for controlled signaling assays.
Cell Migration and Receptor Expression
KISS1-associated research includes cell motility, proliferation, MAPK signaling, radioligand binding, and KISS1R expression measurements. Findings from modified probes or conjugates require interpretation according to their exact molecular identity and experimental model.
Metabolic Signaling Interfaces
Laboratory endpoints include pancreatic-islet morphology, hormone secretion panels, enteroendocrine cell markers, and GLP-1/GIP-associated measurements. These provide assay contexts for studying relationships between kisspeptin and metabolic signaling.
Endothelial and Hepatic Assays
Research contexts include VEGF ELISA, endothelial migration assays, HUVEC proliferation measurements, and hepatic extracellular-matrix markers. Interpret each readout within the defined cell model, concentrations, and controls.
Granulosa-Cell Signaling
The existing description lists let-7b/ITGB7, ERK, PI3K, and Akt pathway research. Laboratory endpoints include progesterone quantification, phosphorylation measurements, flow-cytometric cell-state analysis, and EdU proliferation assays.
