Biological background
Protein function (datasheet): 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. .
Scientific background (datasheet): MAPT, Microtubule-associated protein tau, appears to be enriched in axons. The MAPT gene is assigned to chromosome 17 by hybridization of a cDNA clone to flow-sorted and spot-blotted chromosomes and to 17q21 by in situ hybridization, containing 16 exons. The tau proteins are the product of alternative splicingfrom a single gene that in humans is designated MAPT. Tau proteins are proteins that stabilize microtubules. They are abundant in neurons in the central nervous system and are less common elsewhere. When tau proteins are defective, and no longer stabilize microtubules properly, they can result in dementias such as Alzheimer's disease.
Cellular localization (datasheet): Cytoplasm, cytosol . Cell membrane ; Peripheral membrane protein ; Cytoplasmic side . Cytoplasm, cytoskeleton . Cell projection, axon . Mostly found in the axons of neurons, in the cytosol and in association with plasma membrane components.
Tissue details (datasheet): Expressed in neurons. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system.
Sequence similarities (datasheet): Contains 4 Tau/MAP repeats.
Research relevance and current trends
- Commonly studied in contexts related to Alzheimer's Disease,Cell Type Marker,Cytoskeleton,Cytoskeleton/ECM,Microtubules,Neurodegenerative Disease,Neurology Process,Neuron Marker,Neuroscience,Signal Transduction.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
