Tool Details

  • Tool name: PL1 peptide
  • Alternate names: PL1, FN-EDB and TNC-C binding protein
  • Tool type: Proteins
  • Tool sub-type: Synthetic Peptide
  • Sequence: PPRRGLIKLKTS
  • Cellular/ tissue localisation: Extracellular matrix
  • Expression system: Synthetic
  • Function: Marker
  • Description: PL1 peptide is a short binding peptide which interacts with oncofetal fibronectin extra domain-B (FN-EDB) and tenascin-C C domain (TNC-C) which are both extracellular matrix proteins present in a tumour microenvironment. The targets of PL1 are nearly absent in normal adult tissues making them indicative of solid tumour tissues. It has been shown that this dual-targeted peptide can be used for robust and specific delivery of imaging agents and therapeutic payloads to solid tumours.
