Overview
KPV is the tripeptide Lys-Pro-Val, corresponding to residues 11–13 at the C-terminus of α-melanocyte-stimulating hormone (α-MSH). It is studied as a minimal fragment of the melanocortin peptide family: small enough to be handled as a simple synthetic tripeptide, while retaining activity of interest in the inflammatory-signaling literature. Supplied as a lyophilized solid for laboratory research use only.
In experimental systems, KPV has been investigated in models of NF-κB and cytokine signaling, in intestinal epithelial and colitis models, and in studies of PepT1-mediated di- and tripeptide transport, where its small size makes it a useful substrate. It also appears in keratinocyte and dermal cell-culture work on inflammatory mediators. This material is supplied strictly for in vitro and laboratory research applications and is not intended for human or veterinary use.
