About KPV
KPV (Lys-Pro-Val) is a tripeptide made up of the amino acids lysine, proline and valine. Its sequence matches the last three residues (positions 11-13) of alpha-melanocyte-stimulating hormone (alpha-MSH), a 13-amino-acid peptide cleaved from the precursor protein proopiomelanocortin (POMC).
In published laboratory research, KPV has been examined in cell-culture studies of intracellular signalling in human keratinocytes and in cells expressing the melanocortin-1 receptor (MC1R), of the NF-kB pathway in intestinal epithelial cell lines, and of its uptake by the peptide transporter PepT1.
Specifications
| Parameter | Value |
|---|---|
| Compound | KPV (Lys-Pro-Val, alpha-MSH C-terminal tripeptide) |
| Purity | ≥98% (class-level specification) |
| Format | Lyophilized powder |
| Reconstitution | Sterile water or saline |
| Storage | -20°C; 2-8°C after reconstitution |
Storage
Store at -20°C before reconstitution. Refrigerate at 2-8°C after reconstitution and use within 28 days. KPV is a small, stable tripeptide with good shelf life under proper storage conditions.
Where does the KPV sequence come from?
Alpha-MSH has the sequence Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val, and KPV corresponds to its last three amino acids. Alpha-MSH is one of several peptides cleaved from proopiomelanocortin (POMC), the same precursor protein that gives rise to adrenocorticotropic hormone (ACTH).
In what kind of research is KPV studied?
The published studies summarised on this page are laboratory research: cell-culture work on melanocortin receptor signalling, on the NF-kB pathway and on peptide transport by PepT1. Their results describe observations made under experimental conditions only.
How does KPV differ from full-length alpha-MSH?
Alpha-MSH has 13 amino acids, while KPV consists of only its last three, so KPV is a much smaller molecule. Full-length alpha-MSH binds several melanocortin receptors (MC1R, MC3R, MC4R and MC5R). KPV is studied as a research compound in its own right.
KPV is supplied for research purposes only. Not for human use. Handle in compliance with institutional biosafety guidelines.
