Subcellular Location:

Cytoplasm, cytosol, Cell membrane, Peripheral membrane protein, Cytoplasmic side, Cytoplasm, cytoskeleton, Cell projection, axon

Tissue Specificity:

Expressed in neurons and at a lower level in the liver and kidney. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system.

Protein Length:

Full Length of Mature Protein

Pathway:

Mol. Weight:

78.1 kDa

Purity:

Greater than 90% as determined by SDS-PAGE.

Form:

Liquid or Lyophilized powder

Buffer:

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Research Areas:

Neuroscience

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 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.

Involvement in disease:

May be involved in the pathogenesis of cytoplasmic inclusions (as Mallory bodies) in livers of mice chronically intoxicated with Griseofulvin or DDC (3,5-diethoxycarbonyl-2,4-dihydrocollidine), a model for human alcoholic hepatitis. Alteration of Tau (abnormal phosphorylation and cross-linking) could contribute to Mallory bodies formation and disturbance of microtubule function in alcoholic liver disease.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
