Title: Lipid membranes in and around aqueous multiphase systems

Location: 1167 Biological Sciences

Date and Time: 4 pm on Wednesday, November 6, 2019

Abstract: Living cells take advantage of both lipid membranes and liquid-liquid phase separation to organize their interior volumes. The resulting membrane-bound and membraneless organelles provide regions with different molecular composition, physical properties, and reactivity. This compartmentalization is crucial to cellular function. In some cases, it appears that these two intracellular compartment types may be interacting in vivo to perform their biological functions, for example in signaling and intracellular communication. Simple experimental models for both types of compartments can be generated in vitro, but few studies have yet been done in which both types of assemblies were present together. This presentation will discuss experiments in which lipid assemblies (vesicles, membranes) and aqueous multiphase systems coexist, and will explore ways in which these compartmentalization motifs interact. Such studies can provide fundamental insights into principles underlying biological organization and could lead to greater functionality in artificial cells assembled from the bottom up.
