KPV is a three-amino-acid peptide, lysine-proline-valine. It is the C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH), and it is studied in laboratory models of inflammatory signaling.
What is KPV?
Alpha-MSH is a 13-amino-acid peptide. KPV corresponds to its last three residues (positions 11 to 13). Researchers study KPV because it is much smaller than the parent peptide, which makes it a useful tool for studying which part of alpha-MSH drives its activity in cell and animal models.
