Description
Description
SpecificityThis antibody recognizes human, mouse, and rat Tau.
BackgroundTau is a subunit protein of one of the major markers of Alzheimer disease (AD), the neurofibrillary
tangles. Tau protein has many unusual properties, such as its number of structural
conformations and biochemical modifications (phosphorylation, proteolysis, and glycosylation),
and its many interaction partners (mainly microtubules, but also other cytoskeletal proteins,
kinases, and phosphatases, motor proteins, chaperones, and membrane proteins). The
aggregation of Tau is toxic in cell and animal models, but can be reversed by suppressing
expression or by aggregation inhibitors.
FunctionPromotes 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. {PubMed:21985311, PubMed:32961270}.
