Biowulf 20th Anniversary Seminar: Modeling complex biological membranes
Due to the dynamic nature and constitutional complexity of a biological membrane, a number of critical questions remain unanswered about its effect on function. How does the compositional asymmetry of the plasma membrane determine its role as a “ solvent ” for transmembrane proteins? What are the many roles of cholesterol in membranes and how much is in the inner and outer leaflet of the plasma membrane? Do all lipids play a role in defining the structural and mechanical properties of membranes, or are some purely for signaling? Our unit at the NIH applies molecular and continuum simulations to determine the compositio...
