Tau protein has been shown to be an integral component of Alzheimer paired helical filaments (PHF). However, the extent to which tau is incorporated into PHF has not been clear because the antibodies used to label PHF generally do not have precisely defined epitopes. Here we define the antigenic sites for five monoclonal antibodies that react with tau and(More)
Tau protein undergoes a shift in its molecular mass and its electrophoretic complexity during early postnatal development. We have sequenced a tau cDNA from an adult rat brain expression library and have found two inserted sequences. One of these inserts predicts a fourth repeated sequence homologous to the other three in the carboxyl end of tau that have(More)
We report the cDNA sequence of the squid kinesin heavy chain and compared the predicted amino acid sequence with that of the Drosophila heavy chain as reported by Yang, J.T., Laymon, R.A., and Goldstein, L.S. B. (1989) Cell 56, 879-889). We compared the two kinesin sequences with regard to the predicted physicochemical parameters of hydrophobicity, charge,(More)
How senile plaques and neurofibrillary tangles are linked represents a major gap in our understanding of the pathophysiology of Alzheimer's disease. We characterized a hippocampal neuronal culture system in which tau undergoes maturation in vivo; rat neurons maintained in culture for more than 3 weeks replicated the splicing and phosphorylation changes that(More)
The classical adherens junction that holds epithelial cells together consists of a protein complex in which members of the cadherin family linked to various catenins are the principal components. delta-catenin is a mammalian brain protein in the Armadillo repeat superfamily with sequence similarity to the adherens junction protein p120(ctn). We found that(More)
The growth-associated protein (GAP-43) is considered a crucial component of an effective regenerative response in the nervous system. Its phosphorylation by protein kinase C correlates with long-term potentiation. Sequence analysis of human cDNAs coding for this protein shows that the human GAP-43 gene is highly homologous to the rat gene; this homology(More)
A 3.3-kilobase DNA complementary to human microtubule-associated protein 2 (MAP2) was sequenced by the dideoxy method. The 3' end terminates at an internal EcoRI site before the polyA tail. Due to the arrangement of the cDNA insert in the lambda gt11 vector, the MAP2 fragment is not fused to beta-galactosidase when expressed. The Chou Fasman algorithm for(More)
