Abstract

Nuclear receptors are among the most important intracellular regulating molecules, that convey diverse internal and external signals into regulation of genetic programs. Genetic programming established or modified by these proteins affect virtually all the aspects of life of multicellular organisms. Transcriptional regulation and selectivity promoted by nuclear receptors nourished their intensive research in attempts to decipher complex network of molecular events that promoted by their capacity of transcriptional regulation and to discover molecular rules which define their control, in space and time, over protein-protein and protein-DNA interactions, opening possibilities for developing of more efficient drugs with superior therapeutical values. Within the present project, we plan to study nuclear receptors by X-ray crystallography, small angle X-ray scattering (SAXS), biochemical and biophysical methods as well as by biocomputing simulations, in attempt to decipher what conformational changes of the receptor 3D structures are induced by its binding to specific ligands (agonists and antagonist) and how this influence receptors oligomeric state state and its interactions with coregulating proteins (coactivators and corepressors), and also modify their stability. We aim to gain insights into recognition of the nuclear receptors DNA response elements by a combined approach of protein crystallography, SAXS and fluorescence anisotropy. Finally, we plan to study the role of nuclear receptors dynamics and flexibility in their function, aiming to determine the preferable dissociation pathways of the nuclear receptor ligands from their respective receptors by molecular dynamics simulations and experimental studies of the mobility and solvent accessibility changes using hydrogen/deuterium exchange combined with mass-spectroscopy. It is important to stress that these aims have an immediate impact on rational development of hormone agonists and antagonists; insert themselves within perspectives of scientific and technical development of Brazil in the area of nuclear receptors and are directly related to the interests of pharmaceutical industry, medicine and productive sector.
