Sonia Bañuelos

Researcher (UPV/EHU)

She earned her BSc in 1991 and PhD in 1995 from the University of the Basque Country, her thesis dealing with biophysical studies on membrane–protein interaction. She did postdoctoral research in M. Saraste´s group at the European Molecular Biology Laboratory (EMBL) in Heidelberg, working on structure and function of domains from cytoskeletal proteins. After having held a Ramón y Cajal contract, she is now researcher and lecturer at the University of the Basque Country. Her group is interested on the structure-function relationship and nucleo-cytoplasmic traffic of nucleophosmin, a protein altered in AML leukemia. Molecular interactions (e.g. with Crm1 exportin) are studied to gain insight into NPM functionality and involvement in pathogenesis.
