|Application ||WB, IHC-P, E|
|Other Accession||NP_058519, 294862261|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||Predicted: 83 kDa |
Observed: 90 kDa
|Application Notes||TAU antibody can be used for detection of TAU by Western blot at 1 - 2 µg/ml. Antibody can also be used for immunohistochemistry starting at 5 µg/mL.|
|Target/Specificity||TAU; TAU antibody is human, mouse and rat reactive. Multiple isoforms of TAU are known to exist; this antibody will only detect the two longest isoforms.|
|Reconstitution & Storage||TAU antibody can be stored at 4℃ for three months and -20℃, stable for up to one year.|
|Precautions||TAU Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||MAPTL, MTBT1, TAU|
|Function||Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. 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. 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.|
|Cellular Location||Cytoplasm, cytosol. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cytoplasm, cytoskeleton. Cell projection, axon. Note=Mostly found in the axons of neurons, in the cytosol and in association with plasma membrane components|
|Tissue Location||Expressed in neurons. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system|

The microtubial-associated protein TAU (MAPT), more commonly known as TAU, is is normally a highly soluble protein found predominantly in neurons (1), but accumulations of highly phosphorylated tau protein aggregates are observed in several neurodegenerative diseases including Alzheimer’s disease, progressive supranuclear palsy, corticobasal degeneration, and frontotemporal lobar dementia. It was thought that these pathological tau aggregates were the toxic form of tau, but recent studies indicate that soluble and highly phosphorylated tau species are more closely associated with synaptic dysfunction and cell loss (2,3). Mutations in the TAU gene have also been associated with several of these neurodegenerative diseases (4).
