Structural and functional characterisation of the structure and function of large macromolecular complexes, specially molecular chaperones. Our group has been working over the last years in the structural characterisation of large macromolecular complexes, in particular some molecular chaperones, which are proteins that assist the folding of other proteins. Using mainly electron microscopy, but also biochemical and molecular biology techniques, the group has worked in the structural and functional characterisation of eukaryotic chaperonin CCT and its interaction with some co-chaperones such as PhLP and PFD, and with various substrates. Our group is also interested in using electron tromography to study various cellular structures such as the centrosome. Finally, our group is very interested in the use of new techniques capable of dealing with single molecules. One of these techniques is the so called optical tweezers, which we have, in collaboration with the group of Dr. L Carrascosa, installed in Spain for the first time. This technique will allow us, among other things, to characterise the forces involved in the conformational changes of various protein complexes, among them CCT.
