Our group studies the functional regulation of proteins belonging to the nuclear receptor superfamily. We are specifically focused on the elucidation of the molecular mechanism of action of a group of proteins known as molecular chaperones, which affect the properties of a variety of transcription factors (i.e. their subcellular transport, biological activity, stability, pharmacological regulation by novel drugs, etc.). We analyse the consequences of those regulations on elemental processes of the cell such as cell differentiation, cell division, metabolism regulation and the apoptosis programme (cell death).
