WebTau is a complex protein that is made in 6 varieties, or splice variants, broadly grouped into the 3R and 4R categories. In 3R tau, exon 10 of the tau gene is excluded from the pre-mRNA during the splicing process, and this in turn excludes one of the microtubule binding regions (MBTRs) such that the resulting tau protein has 3 of these regions ... A new study from MIT chemists has revealed how two types of tau proteins, known as 3R and 4R tau, mix together to form these tangles. The researchers found that the tangles can recruit any tau protein in the brain, in a nearly random way. This feature may contribute to the prevalence of Alzheimer’s disease, the researchers say.
