Research interests

Membrane trafficking and signalling in polarised cells. Role of multi-PDZ domain proteins in cancer formation, metastasis and tumor invasion.
Our group is interested in the regulation of membrane trafficking and its relation to human diseases. In particular we are interested in the molecular mechanism leading to Lowe syndrome, a X-linked disease characterized by congenital cataracts, mental retardation and kidney failure. Moreover, we analyze the molecular function of multi-PDZ domain proteins (PTPN13 and FRMPD2) in vesicular trafficking and signal transduction as well as their role in cancer development and progression.
