Dabcyl-LNKRLLHETQ-Edans (Fluorigenic PEXEL peptide) is a biologically active peptide. It serves as a FRET substrate peptide for Plasmepsin V (PMV), derived from the conserved Plasmodium export element (PEXEL) motif of histidine-rich protein II (HRPII). PMV functions as an endoplasmic reticulum aspartic protease that specifically recognizes and cleaves the RXL sequence within the PEXEL motif of proteins exported by Plasmodium falciparum, facilitating their translocation into host red blood cells.
