Aggregated Tau Protein (Aggregated Tau)

Target
Aggregated Tau
Molecular classification
Protein aggregate, Intracellular protein, Microtubule-associated protein (modified)
01

Overview

Aggregated tau protein refers to the abnormal accumulation and clustering of tau proteins into insoluble aggregates within neurons, a pathological hallmark of Alzheimer's disease (AD) and other tauopathies. Hyperphosphorylation and truncation of tau are key drivers of aggregation, leading to disruption of microtubule function, impaired axonal transport, and neuronal degeneration. It is a therapeutic target.
