The Golgi apparatus of interphase mammalian cells is located in close physical proximity to the centrosome, the major microtubule organizing center of the cell. The reason for this specific localization of the Golgi apparatus, which is unique to mammalian cells, is not well understood.
There is increasing evidence in support of a functional link between the Golgi apparatus and the centrosome during interphase and mitosis. Our research focuses on determining the mechanism by which Golgi proteins regulate the centrosome during the cell cycle. Specifically, we are interested in how the peripheral Golgi proteins, GM130 and GRASP65, control the organization and function of the centrosome during interphase and mitosis, respectively. In our studies, we are using a broad repertoire of techniques of cell and molecular biology and of biochemistry.
This pericentriolar region a mammalian cell is also occupied by the membrane-bound inclusion that is inhabited by the gram-negative bacterium Chlamydia trachomatis. Chlamydiae have to acquire lipids from the host cell in order to grow and replicate. We are interested in understanding the molecular mechanism by which Chlamydia reroutes host trafficking pathways to obtain host host derived proteins and lipids.
We are also investigating how the chlamydial inclusion interacts with the Golgi apparatus, the ER and the centrosome.
