Enables several functions, including Hsp90 protein binding activity; chaperone binding activity; and enzyme binding activity. Involved in several processes, including intrinsic apoptotic signaling pathway in response to oxidative stress; mRNA transport; and positive regulation of long-term synaptic depression. Located in several cellular components, including axon; cytoplasmic side of plasma membrane; and neuronal cell body. Colocalizes with microtubule. Used to study brain disease (multiple); cognitive disorder (multiple); obesity; and tauopathy (multiple). Biomarker of middle cerebral artery infarction. 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). [provided by Alliance of Genome Resources, Apr 2022]
