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.
