What is KPV?<\/h2>\n

KPV is a tripeptide made up of three amino acids: lysine (K), proline (P), and valine (V) \u2013 the name is also the sequence in one-letter code. These residues form the C-terminal end of \u03b1-melanocyte-stimulating hormone (\u03b1-MSH), a 13 amino acid long melanocortin peptide. In the scientific literature, KPV is therefore often referred to as \"\u03b1-MSH (11\u201313)\".<\/p>\n

This brevity makes KPV interesting for laboratory work: fragment peptides allow individual sections of a larger hormone to be considered in isolation, and a tripeptide is very easy to characterise analytically \u2013 low molecular mass, clear mass spectrum, easily assignable side peaks. KPV is produced synthetically via solid-phase peptide synthesis with preparative chromatography and freeze-drying; the result is a white lyophilised powder in a sealed vial.<\/p>\n\n

Molecular profile & target structure<\/h2>\n

The molecular formula is C\u2081\u2086H\u2083\u2080N\u2084O\u2084, the CAS number is 67727-97-3. The three building blocks contribute different properties: Lysine carries a basic, positively charged side chain, proline is the only proteinogenic amino acid whose side chain is re-bonded to the backbone nitrogen (pyrrolidine ring), which restricts the conformational freedom of the chain, valine is small and hydrophobic.<\/p>\n

Regarding the target structure, the literature describes a differentiated picture: While complete \u03b1-MSH is considered the classic ligand for melanocortin receptors, KPV is investigated in several studies in connection with the peptide transporter PepT1 (SLC15A1) \u2013 a transport protein for di- and tripeptides, which is described in, among others, intestinal epithelial and immune cell lines.<\/p>\n\n
