Structuring membrane proteins as tools in material science

Abstract [en]

Integral membrane proteins are interesting from a material science point of view due to their wide variety of functions and the possibility to create a functional barrier or carrier system. By using the same mols. found in nature, the structure and properties can be mimicked and utilized in designed materials. Two membrane proteins derived from yeast, Yop1p and Rtn1p, have been engineered, heterogeneously expressed and purified using a GFP-fusion platform. Both proteins are membrane spanning and can be found in all eukaryotes in which they are used for structural control of the endoplasmatic network. Yop1p and Rtn1p have previously been shown to induce tubules in lipid vesicles and we have seen that by altering the concn. of structuring protein as well as the shape of the lipids, the vesicle morphol. can be controlled.
