Webb18 feb. 2015 · The pH-low insertion peptide (pHLIP) targets acidic diseases such as cancer. The acidity of the environment causes key aspartic acids in pHLIP to become protonated, causing the peptide to insert into membranes. Here we investigate how the negative charge of the membrane influences how pHLIP enters and exits the lipid bilayer. WebbWe have previously observed the spontaneous, pH-dependent insertion of a water-soluble peptide to form a helix across lipid bilayers. We have now used a related peptide, pH (low) insertion peptide (pHLIP), to translocate cargo molecules attached to its C terminus across the plasma membranes of living cells.
