Pseudophosphorylation

WebFeb 1, 2011 · Hyperphosphorylation of tau protein is associated with neurofibrillary lesion formation in Alzheimer's disease and other tauopathic neurodegenerative diseases. It fosters lesion formation by increasing the concentration of free tau available for aggregation and by directly modulating the tau aggregation reaction. WebStructural analyses of the doubly-charged pseudophosphorylation mutants suggest that alterations in an interdomain salt bridge between residues R4 and D100 results in impaired signal transmission from RLC to the catalytic domain of SMM, which explains the low ATPase activity of these mutants. Our results demonstrate that phosphorylation ...

WebApr 5, 2006 · In vitro, pseudophosphorylation of S422 (S422E) was capable of inhibiting cleavage. These results were not due to manipulation of the protein, but specifically to the pseudophosphorylation at S422, because mutating the serine to an alanine resulted in cleavage kinetics indistinguishable from that of wild-type tau. WebThe resultant “pseudophosphorylation” mutants imitate phosphorylation-induced changes in the structure and microtubule-binding function of tau ( 23 , 24 , 25 , 26 ), react with many phosphoepitope-selective antibodies ( 27 ), and reportedly can promote or inhibit tau fibrillization depending on the sequence context investigated ( 24 , 25 , 27 , 28
