Recombinant Rat MAPT Protein (2-752 aa), His-tagged

• Cat.No.: MAPT-647R
• Product Overview: Recombinant Rat MAPT Protein (2-752 aa) is produced by E. coli expression system. This protein is fused with a 6xHis tag at the N-terminal. Protein Description: Full Length of Mature Protein.

Specification

• Description: Promotes microtubule assbly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma mbrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.

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.
