Membrane proteins in health and disease.

N-linked glycosylation is the most frequent modification of secretory and membrane proteins in eukaryotic cells. Many human diseases are caused by inherited or acquired modifications in membrane proteins and several disorders are associated with deficiencies in the N-linked glycosylation pathway. Some diseases are caused by mutations that lead to a loss of function of the membrane protein expressed from the gene. Others arise when a specific protein undergoes a conformational rearrangement and/or aggregates.

At present, there are very few clues how mutations in genes of different membrane proteins cause such diverse disorders as cystic fibrosis, Alzheimer's diseases and lipodystrophy. To better understand and explain specific roles of membrane proteins involved in human diseases, work in our lab is focused on membrane protein topologies, using a glycosylation mapping approach. We have a special interest in problems related to the oligosaccharyl transferase complex that modifies proteins by glycosylation.
