Mechanism related to the onset of various genetic diseases revealed
Researchers at the Department of Biochemistry and Molecular Biology of Universitat Autonoma de Barcelona (UAB) have revealed the process by which proteins with a tendency to cause conformational diseases such as amyotrophic lateral sclerosis, familial amyloidotic polyneuropathy, familial amyloidotic cardiomyopathy, etc. finally end up causing them. Researchers have carried out an analysis of their 3D structure and studied why these proteins finally become toxic although they are correctly folded, an indicator that they are functioning correctly. The answer can be found in the separation of the proteins, which under normal conditions are found in groups of two or more, caused by a genetic mutation in their composition. Researchers believe this discovery, published recently in the journal PLoS Computational Biology, could also be the cause of other diseases of unknown origins...
