Enables DNA binding activity; microtubule binding activity; and protein kinase binding activity. Involved in negative regulation of tubulin deacetylation; regulation of cellular response to heat; and regulation of response to DNA damage stimulus. Acts upstream of or within several processes, including adult walking behavior; generation of neurons; and transport along microtubule. Located in several cellular components, including cytoskeleton; glial cell projection; and postsynaptic density. Is expressed in several structures, including gut; nervous system; sensory organ; smooth muscle tissue; and urinary system. Used to study Alzheimer's disease. Human ortholog(s) of this gene implicated in dementia (multiple); neurodegenerative disease (multiple); progressive supranuclear palsy; and temporal lobe epilepsy. Orthologous to human MAPT (microtubule associated protein tau).
