DSPE-PEG2000-GRKKRRQGGGPPQ

DSPE-PEG2000-GRKKRRQGGGPPQ is a phospholipid-PEG conjugate that is often used as a coating or surfactant for nanoparticles and liposomes. The peptide sequence, GRKKRRQGGGPPQ, includes arginine (R), lysine (K), glycine (G), and proline (P) residues, and is a variant of the Antennapedia homeodomain-derived peptide (Penetratin), which has cell-penetrating properties. This peptide sequence allows for enhanced cellular uptake of the coated particles by interacting with cell surface receptors and facilitating their internalization.
