A hallmark of Alzheimer’s Disease (AD) is the aggregation of hyperphosphorylated tau protein into neurofibrillary tangles. Tau localizes to both the cytoplasm and the nucleus of neuronal cells; however, its nuclear role has not been fully defined. Tau has recently been shown to bind to purine-pyrimidine (R/Y) repeats in DNA and stabilize them into Z-DNA. Evidence from our lab suggests that the binding of tau to R/Y repeats causes transcriptional changes of the NOS1 gene. Six major isoforms of tau exist in neurons. These isoforms fall into two groups, denoted as 3R tau and 4R tau, and are found at …
