Description générale

The gene microtubule associated protein tau (MAPT) is localized on human chromosome 17q21.3. It is expressed in neurons, more specifically in axons.

Actions biochimiques/physiologiques

Microtubule associated protein tau (MAPT) aids in the assembly and maintenance of microtubule structure. Loss of expression of MAPT results in developmental delay and learning disability. The protein has been associated with pathology of Alzheimer′s disease (AD).
Isoform of Tau, variant 1N3R, having 3 microtubule binding repeats (R) and one amino terminal insert (N).

Reconstitution

Lyophilized from MES, pH 6.8, containing NaCl and EGTA. When reconstituted in water to a protein concentration of 1 mg/mL, the resulting buffer will have ~50 mM MES, pH 6.8, 100 mM NaCl, and 0.5 mM EGTA.

The morphology of a neuron is determined by its cytoskeletal scaffolding. Thus proteins that associate with the principal cytoskeletal components such as the microtubules have a strong influence on both the morphology and physiology of neurons. Tau is a microtubule-associated

Tau proteins consist of a family of proteins, heterogeneous in size, which associate with microtubules in vivo and are induced during neurite outgrowth. In humans, tau is one of the major components of the pathognomonic neurofibrillary tangles in Alzheimer's disease

We have determined the sequences of isoforms of human tau protein, which differ from previously reported forms by insertions of 29 or 58 amino acids in the amino-terminal region. Complementary DNA cloning shows that the insertions occur in combination with
