Abstract

Tau protein is an integral component of paired helical filaments, a pathological feature of Alzheimer's disease. tau extracted from these filaments displays decreased electrophoretic mobility due to aberrant phosphorylation. Here we show that recombinant human tau can be phosphorylated by cAMP-dependent protein kinase resulting in decreased electrophoretic mobility. Phosphorylation of tau by cAMP-dependent protein kinase caused a 92% decrease in the maximum rate of tau-induced microtubule assembly. The sites of phosphorylation were identified by digesting phosphorylated tau with proteases, separating the peptides by reversed-phase HPLC, and analyzing the isolated peptides by liquid-secondary ion mass spectrometry and solid-phase N-terminal sequencing. Five phosphorylation sites were identified, two of which were located within microtubule binding domains. One site was previously shown to be the sole phosphorylation site for CaM kinase II; phosphorylation at this site by CaM kinase II was sufficient to cause decreased electrophoretic mobility (Steiner, B., Mandelkow, E. M., Biernat, J., Gustke, N., Meyer, H. E., Schmidt, B., Mieskes, G., Soling, H. D., Drechsel, D., Kirschner, M. W., Goedert, M., and Mandelkow, E. (1990) EMBO J. 9, 3539-3544). Thus two different second messenger-dependent protein kinases can phosphorylate tau at the same site and induce a shift in tau mobility like that seen in Alzheimer's disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
