21. Insertion and Topology of Inner Membrane Proteins in Escherichia coli
Abstract : Integral membrane proteins are found in all cellular membranes and fulfil many of the functions that are central to life. They maintain the membrane structure, but are also involved in the regulation of different cellular processes. READ MORE

22. EmrE, a puzzling transporter : Assembly, biogenesis and evolution of a dual-topology membrane protein
Abstract : Biological membranes are the key to cell existence, as they are able to both isolate and connect their interior with the environment. Membranes are composed of lipids and proteins that create a semi-permeable barrier; because the lipid bilayer stops free diffusion of most molecules and ions, membrane proteins play an important role in connecting the interior of the cell with its environment.

23. Functional Characterization of the Yeast Tumour Suppressor Homologue Sro7p
Abstract : Correct targeting of newly synthesized proteins to appropriate domains of the cell membrane is crucial to cellular architecture, polarity and function, making it no surprise that many proteins of the secretory machinery are conserved throughout evolution. This work presents a functional characterisation of the Saccharomyces cerevisiae cell polarity protein and tumour suppressor homologue, Sro7p. READ MORE

24. Insertion studies of model transmembrane segments into bacterial and eukaryotic membranes
Abstract : Cells are encapsulated by a biological membrane in order to separate the cell interior from the surrounding environment. Different lipids and proteins compose the membrane and present a semi-permeable barrier for the diffusion of ions and molecules across the lipid bilayer. READ MORE

25. Dynamics of peptide chains during co-translational translocation, membrane integration & domain folding
Abstract : The biosynthesis of proteins occurs at the ribosomes, where amino acids are linked together into linear chains. Nascent protein chains may undergo several different processes during their synthesis. Some proteins begin to fold, while others interact with chaperones, targeting factors or processing enzymes.
