Phosphatidylserines 86-104 pitrilysin metallopeptidase 1 Homo sapiens 4-7 28802697-5 2017 The MP1-lipid membrane interaction was studied using Langmuir phosphatidylcholine and phosphatidylserine (PS) monolayers as model membrane systems. Phosphatidylserines 106-108 pitrilysin metallopeptidase 1 Homo sapiens 4-7 28802697-6 2017 PS was chosen since this negatively charged lipid was found predominantly on the outer leaflet of tumor cells, and it enhances MP1 activity for PS-containing membranes to a greater extent than for other negatively charged lipids. Phosphatidylserines 0-2 pitrilysin metallopeptidase 1 Homo sapiens 127-130 28802697-6 2017 PS was chosen since this negatively charged lipid was found predominantly on the outer leaflet of tumor cells, and it enhances MP1 activity for PS-containing membranes to a greater extent than for other negatively charged lipids. Phosphatidylserines 144-146 pitrilysin metallopeptidase 1 Homo sapiens 127-130 28802697-7 2017 MP1 incorporated into anionic PS monolayers, which show a liquid-expanded (LE) phase or LE-liquid-condensed (LC) phase coexistence, up to lipid-packing densities higher than those of cell membranes. Phosphatidylserines 30-32 pitrilysin metallopeptidase 1 Homo sapiens 0-3 28274844-3 2017 In agreement with this requirement, phosphatidylserine lipids are translocated to the outer leaflet of cells, and are available for MP1 binding, depending on the presence of liquid-ordered domains. Phosphatidylserines 36-54 pitrilysin metallopeptidase 1 Homo sapiens 132-135 28274844-4 2017 Here, we investigated the effect of PS on MP1 activity when this lipid is reconstituted in membranes of giant or large liposomes with different lipid-phase states. Phosphatidylserines 36-38 pitrilysin metallopeptidase 1 Homo sapiens 42-45 28274844-8 2017 Based on our findings, we propose that the physicochemical properties of cancer cell membranes, which possess a much higher concentration of PS than normal cells, renders them susceptible to MP1 binding and lytic pore formation. Phosphatidylserines 141-143 pitrilysin metallopeptidase 1 Homo sapiens 191-194 26331251-8 2015 Therefore, PS and PE lipids synergistically combine to enhance membrane poration by MP1, implying that the combined enrichment of both these lipids in the outer leaflet of cancer cells is highly significant for MP1"s anticancer action. Phosphatidylserines 11-13 pitrilysin metallopeptidase 1 Homo sapiens 84-87 26331251-8 2015 Therefore, PS and PE lipids synergistically combine to enhance membrane poration by MP1, implying that the combined enrichment of both these lipids in the outer leaflet of cancer cells is highly significant for MP1"s anticancer action.
