Recombinant Human HSPA1A protein, His-tagged

• Cat.No.: HSPA1A-526H
• Product Overview: Recombinant Human HSPA1A(amino acids 1-641) fused with His tag at N-terminal was expressed in E. coli.

Specification

• Description: Hsp70 is a human heat shock protein. Hsp70 is an important part of the cell's machinery for protein folding, and help to protect cells from stress. In most species, there are many proteins that belong to the hsp70 family. Some of these are only expressed under stress conditions, while some are present in cells under normal growth conditions and are not heat-inducible. They can be found in different cellular compartments (nuclear, cytosolic, mitochondrial, endoplasmic reticulum, etc.

Q&As

How is HSPA1A associated with other proteins or diseases?

HSPA1A has multiple associations with other proteins and diseases. For example, it may interact with the p53 protein to affect the occurrence and progression of tumors, and may also be associated with neurodegenerative diseases and be involved in the pathogenesis of diseases such as Alzheimer's disease.

What is the role of HSPA1A in stressful conditions?

HSPA1A can protect cells from damage through synergistic effects with other molecular chaperones such as HSP70 and HSP40 under stressful conditions. In addition, it can also be involved in the regulation of apoptosis.

Does HSPA1A have therapeutic potential?

Yes, HSPA1A has therapeutic potential. In tumor therapy, drug suppression or gene therapy against HSPA1A may become a new way to treat tumors. At the same time, inhibitors against HSPA1A are also being developed.

What are the health effects of aberrant expression of HSPA1A?

Aberrant expression of HSPA1A may be associated with a variety of diseases, especially cancer, neurodegenerative diseases, etc. For example, in tumors such as lung, breast, and colon cancer, HSPA1A expression levels may be abnormally elevated.

How is the level of HSPA1A detected?

Levels of HSPA1A can be detected by methods such as immunohistochemistry, western blotting, and real-time PCR, which can assess the amount of HSPA1A in tissues and cells.

How is HSPA1A involved in the proper folding and transport of proteins?

This protein can bind to unfolded proteins to form multimeric complexes that facilitate proper folding and transport of proteins. In addition, it can also work synergistically with other molecular chaperones such as HSP70 and HSP40 to participate in the correct folding and transport of proteins.
