Supplementary information

4R Tau also known as the 4-repeat tau protein plays a significant role in the stabilization of microtubules in neurons. This protein appears mainly in the human central nervous system where it assists in axonal structure and transport. 4R Tau has a molecular weight of approximately 65 kDa. The expression of 4R Tau occurs mostly in neurons although its presence can also be detected in other cell types within the brain.
Biological function summary

4R Tau is a component essential for the assembly and maintenance of neuronal microtubules. It regulates microtubule dynamics by binding and enhancing their stability important for maintaining cellular and axonal integrity. In mature neurons 4R Tau exists as part of a complex with tubulin forming an important element for axonal morphology. Its function extends further into modulating neuronal growth and signal transmission which directly impacts neural connectivity.

Pathways

4R Tau is integral within the microtubule-associated protein tau (MAPT) signaling pathways. It interacts with other proteins that influence microtubule assembly and stability such as tubulin and MAP2 playing a significant role in cytoskeletal development. Additionally 4R Tau is involved in the protein folding pathways regulated by chaperones like Heat Shock Protein 70 (Hsp70) which affect its aggregation and function within neural cells.

4R Tau is closely associated with neurodegenerative conditions such as Alzheimer's disease and frontotemporal dementia. Aberrant phosphorylation and aggregation of 4R Tau drive pathological tau tangles which disrupt neural networks and lead to cognitive decline. In Alzheimer’s the protein's dysfunction is linked with amyloid-beta peptide which accelerates tau pathology progression. Similarly in frontotemporal dementia 4R Tau's abnormal activity is influenced by interactions with proteins such as TDP-43 highlighting its central role in these neurodegenerative disorders.

Target data

Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity (PubMed : 21985311). The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both (PubMed : 21985311, PubMed : 32961270). Axonal polarity is predetermined by TAU/MAPT localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.
