Discovery of an unexpected function of a protein linked to neurodegenerative diseases
This is a microscope image of polytene chromosomes from Drosophila melanogaster, in which, using staining techniques, scientists have visualized the protein dDsk2, a molecule never previously associated with chromatin Until today, the proteins known as ubiquitin receptors have been associated mainly with protein degradation, a basic cell cleaning process. A new function now described for the protein dDsk2 by the team headed by Ferran Azorín, group leader at the Institute for Research in Biomedicine (IRB Barcelona) and CSIC research professor, links ubiquitin receptors for the first time with the regulation of gene expression. This discovery, published today in Nature Communications, opens up a double scenario, one focused on basic epigenomic research and the other biomedical, because of the link between dDsk2 and neurodegenerative diseases.
