Tau protein containing many phosphorus groups (P-tau) can produce neurofibrillary tangles, which are twisted protein fragments that develop in nerve cells and disrupt the cells' ability to transport signals. Neurofibrillary tangles are formed by hyperphosphorylation of a microtubule-associated protein known as tau, causing it to aggregate, or group, in an insoluble form. 70% decrease in microtubule-binding after in vitro phosphorylation of mutant protein.
