A15091A_HRP_Tau-Phospho_Antibody_041218_merged
IHC staining of HRP conjugated anti-Tau Phospho (Ser262) antibody (clone A15091A) on formalin-fixed paraffin-embedded normal (left panel) and Alzheimer's disease (right panel) human brain tissues. Following antigen retrieval using Sodium Citrate H.I.E.R. (Cat. No. 928602), the tissues were incubated with 5 µg/mL of the primary antibody overnight at 4°C. DAB was used for detection followed by hematoxylin and bluing solution counterstaining, according to the protocol provided. The images were captured with a 40X objective. Scale bar: 50 µm.

Description

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 hyperphosphorylation, 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.

Antigen Details

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
Biology Area
Cell Biology, Neurodegeneration, Neuroscience, Protein Misfolding and Aggregation
