The prion protein (PrP) is currently one of the most studied molecules in the neurosciences. It is the main cause of a group of neurological diseases collectively called transmissible spongiform encephalopathies that severely affect both humans and a variety of mammals. Much effort has been directed to understanding the molecular basis of PrP activity, both(More)
As essential components of the molecular machine assembling heterochromatin in eukaryotes, HP1 (Heterochromatin Protein 1) proteins are key regulators of genome function. While several high-resolution structures of the two globular regions of HP1, chromo and chromoshadow domains, in their free form or in complex with recognition-motif peptides are(More)
Proteins are structurally dynamic molecules that perform specialized functions through unique conformational changes accessible in physiological environments. An ability to specifically and selectively control protein function via conformational modulation is an important goal for development of novel therapeutics and studies of protein mechanism in(More)
Sirtuin genes have been associated with aging and are known to affect multiple cellular pathways. Sirtuin 2 was previously shown to modulate proteotoxicity associated with age-associated neurodegenerative disorders such as Alzheimer and Parkinson disease (PD). However, the precise molecular mechanisms involved remain unclear. Here, we provide mechanistic(More)
α-Synuclein misfolding and aggregation is a hallmark in Parkinson's disease and in several other neurodegenerative diseases known as synucleinopathies. The toxic properties of α-synuclein are conserved from yeast to man, but the precise underpinnings of the cellular pathologies associated are still elusive, complicating the development of effective(More)
MOTIVATION A large fraction of eukaryotic proteins contain unstructured tails or linkers. The presence of flexible regions allows these systems to experience a high level of mobility facilitating their biological function. The complex nature of protein rotation in such flexible modular systems precludes a straightforward application of hydrodynamic methods(More)
