The pHLIP binds to lipid … WebbAn antimicrobial peptide, known as V13K, was utilized as the framework to study the effects of charge, hydrophobicity and helicity on the biophysical properties and biological activities of α-helical peptides. Six amino acids (Lys, Glu, Gly, Ser, Ala, and Leu) were individually used to substitute the original hydrophobic valine at the selected sixteenth …
WebbIn view of that, recent studies have reported a pH low insertion peptide (pHLIP) derived from the α-helix of the bacteriorhodopsin protein, which has a unique ability to sense pH in the vicinity of the cell membrane and could insert itself across the cell membrane by forming an α-helix spontaneously [18], [19].

For the infection RAW 264.7 cells cultured in RPMI-1640 supplemented with 10% fetal calf serum (FCS) (Gibco) were seeded in the same medium on cover glasses (18 × 18 mm Menzel Gläsercoverslips, Thermo Fisher Scientific, … WebbA low-pH insertion peptide (pHLIP) specifically targeting the acidic microenvironments of tumors has been employed to label RNA or nanoparticles to enhance the accumulation of these molecules in tumors and to enhance their therapeutic effects ( 24 - 27 ).
WebbThe difference is possibly related to shallower insertion depth the E11A mutant, and consequently lower burial of the N-terminal peptide charge . Finally, of note is the highest rate of lipid protrusions generated by the wt − HAfb with E11 deprotonated, whose occurrence in real life scenarios cannot be excluded given the exposure of the hairpin …
