Description

Description générale

Microtubule-associated protein Tau (UniProt P10636; also known as Neurofibrillary tangle protein, Paired helical filament-tau, PHF-tau) is encoded by the MAPT (also known as TAU, MAPT1, MTBTL) gene (Gene ID 4137) in human. Neurofibrillary tangles (NFTs), composed of truncated and hyperphosphorylated Tau, are a common feature of aging-related neurodegenerative diseases, including Alzheimer′s disease (AD). In addition to caspases-mediated cleavage at Asp421, Tau can also be cleaved at Asn255 and Asn368 by the lysosomal cysteine proteinase asparagine endopeptidase (AEP). AEP is upregulated in aged brain, as well as n human AD brain and tau P301S–transgenic mice with synaptic pathology and behavioral impairments. AEP-mediated tau cleavage abolishes tau microtubule assembly function, induces tau aggregation and triggers neurodegeneration. AEP knockout or functional blockage in tau P301S mice leads to a reduction of tau hyperphosphorylation, protection against memory loss, and a reduction in tau P301S–triggered pathological and behavioral defects.

Spécificité

Specifically recognizes AEP-generated Tau fragments with N368 as the c-termus. Does not react with full-length Tau or Tau fragments with other cleaved c-termus. Uniprot P10636 lists 9 human tau isoforms produced by alternative splicing. The N368 designation was originally assigned to this polyclonal antiserum based on Asp368 of isoform 8 (Tau-F, Tau-4), which is equivalent to N685 of isoform 1 (PNS-tau), N279 of isoform 2 (Fetal-tau), N243 of isoform 3 (Tau-A), N308 of isoform 4 (Tau-B), N337 of isoform 5 (Tau-C, Tau-3), N310 of isoform 6 (Tau-D), N339 of isoform 7 (Tau-E), and N703 of isoform 9 (Tau-G).
