Biolegend, 948802, Purified anti-Tau, 269-281 Recombinant Antibody, 100μg

Tau protein promotes microtubule assembly and stability. Tau is abundant in neurons of the central nervous system, and is expressed at low levels in astrocytes and oligodendrocytes. Abnormal hyper-phosphorylation, aggregation, and toxic gain of function of tau is associated with several neurological disorders, including Alzheimer’s disease (AD). The major building block of neurofibrillary lesions in AD brains consists of paired helical filaments (PHFs) of abnormally hyperphosphorylated tau. Six isoforms of tau are generated by alternative splicing of the MAPT gene. These isoforms are distinguished by the number of tubulin binding domains, 3 (3R) or 4 (4R), in the C-terminal of the protein and by one (1N), two (2N), or no (0N) inserts in the N-terminal domain. Tau isoforms are differentially expressed during development.
100μg
Verified Reactivity: Human, Mouse
Antibody Type: Recombinant
Host Species: Rat
Immunogen: Partial recombinant human Tau protein
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide

RRID: AB_2910513 (BioLegend Cat. No. 948801) AB_2910513 (BioLegend Cat. No. 948802)
Structure: Unmodified Tau isoforms have an apparent molecular weight ranging from 33-79 kD. Additional high and low molecular weight Tau species have been observed in brain tissues.
Distribution: Tissue distribution: central nervous system, peripheral ganglia and nerves, kidney, skeletal, and heart muscle. Cellular distribution: cytoskeleton, nucleus, plasma membrane, and cytosol.
Function: Tau promotes microtubule assembly and stability. The short tau isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.
Interaction: Tau interacts with Sequestosome-1, Peptidyl-prolyl cis-trans isomerase FKBP4, Casein kinase I isoform delta, Serine/threonine-protein kinase Sgk1, Laforin, Alpha-synuclein
Cell Type: Neurons
Biology Area: Cell Biology, Neurodegeneration, Neuroscience, Protein Misfolding and Aggregation
Molecular Family: Tau
