Functional narrative    

Microtubule-associated protein tau isoform Tau-F interacts with alpha and beta tubulin, as well as other microtubule-associated protein tau isoforms to promote microtubule assembly and stability. This isoform is generally found in the cytosol, axons of neurons, or involved with the plasma membrane. Microtubule-associated protein tau isoform F is associated with many forms of dementia including Alzheimer’s disease. This isoform forms paired helical filaments (PHFs) leading to the formation of neurofibrillary tangles, a characteristic symptom of this disease. Also, if point mutations occur in the repeat region of this protein, its function is lost and may lead to other forms of dementia. This entry is a characterization of the 441 residue isoform (Tau-F). The sequence is from Geodert (1989) and is an alternatively spliced isoform of Swiss-Prot TAU_HUMAN (P10636). Microtubule-associated protein tau isoform Tau-F is an intrinsically disordered protein. It has the ability to form dimers, trimers, etc. During dimerization the area characterized by four pseudo repeats becomes ordered to form a more stable multimer.
