Recombinant Human Tau-441 (L266V)

• Cat.No.: MAPT-135H
• Product Overview: Recombinant human tag-free Tau-441 (L266V) was expressed in E. coli cells.

Specification

• Description: Tau-441 or Tau-F is a member of the Tau family of proteins which function to stabilize the microtubules by binding to them. Tau proteins are subject to phosphorylation and this phenomenon regulates the association of the Tau protein with the microtubules. Deposits of Alzheimer"s disease AD-associated proteins, such as hyperphosphorylated Tau, as well as other shared misfolded proteins, such as, β-amyloid precursor protein (βAPP), ubiquitin, and various chaperones and protein kinases are thought to play a pathologic role in the cognitive decline and muscular failure. Malfunctioning of Tau proteins is associated with microtubules disintegration and collapsing of the neuronal transport system.

Q&As

How to assess the degree of abnormal aggregation of MAPT protein?

The degree of abnormal aggregation of MAMAP proteins can be assessed by a variety of methods, such as immunohistochemistry, immunofluorescence staining, Western blot, etc. These methods can detect and quantify abnormally aggregated MAPT proteins.

What is the relationship between MAPT protein and nerve cytoskeleton?

The MAPT protein is closely related to the nerve cytoskeleton. It is involved in regulating axon formation and maintenance, cytosolic flow, and the normal function of neurons by binding and stabilizing microtubules.

What are the interactions of the MAPT protein with other proteins in the nervous system?

MAPT protein interacts with other proteins in the nervous system, such as α-synuclein, β-kinigin, etc. These interactions may be involved in regulating the structure and function of neurons.

Is there a mechanism that regulates the expression of MAPT protein?

Yes, the expression of MAPT protein is affected by a variety of regulatory mechanisms, including transcriptional regulation, splicing regulation, phosphorylation regulation, etc. These regulatory mechanisms are essential for maintaining normal MAPT protein levels and function.

What are the future directions for MAPT protein research?

Future research directions include further elucidating the mechanism of abnormal aggregation and phosphorylation of MAPT protein, exploring the pathogenesis of genetic diseases associated with MAPT gene, finding therapeutic strategies to intervene in abnormal aggregation of MATT, and developing biomarkers related to MAPT protein for early diagnosis and therapeutic monitoring.

How about the applications of MAPT protein in clinical diagnosis?

The MAPT protein plays an important role in clinical diagnosis. By measuring the level of the MAPT protein in the blood or cerebrospinal fluid, it can help identify different types of neurodegenerative diseases, such as Alzheimer's disease and prefrontal temporal dementia.
