Abstract
Lysine acetylation of the neuronal Tau protein was described as a novel mechanism of posttranslational regulation of Tau functions with important outcomes in microtubule binding and aggregation processes related to Alzheimer's disease. Here, we unravel at a per-residue resolution the acetylation pattern of full-length Tau by the Creb-binding protein (CBP) acetyltransferase using high-resolution NMR spectroscopy. Our study gives a quantitative overview of CBP-mediated acetylation and examines the catalytic proficiency since non-enzymatic reaction with acetyl-coenzyme A occurs in vitro. Furthermore, we have investigated with this characterized acetylated Tau the effect of acetylation on Tau fibrillization in a heparin-induced aggregation assay and on heparin binding.

A metabolomic comparison of mouse models of the Neuronal Ceroid Lipofuscinoses
Abstract The Neuronal Ceroid Lipofuscinoses (NCL) are a group of fatal inherited neurodegenerative diseases in humans distinguished by a common clinical pathology, characterized by the accumulation of storage body material in cells and gross brain atrophy. In this study, metabolic changes in three NCL mouse models were examined looking for pathways correlated with neurodegeneration. Two mouse models; motor neuron degeneration (mnd) mouse and a variant model of late infantile NCL, termed the neuronal ceroid...

Post-translational protein modifications (PTMs) such as phosphorylation and acetylation regulate a large number of eukaryotic signaling processes. In most instances, it is the combination of different PTMs that "encode" the biological outcome of these covalent...
