Recombinant Human Heat Shock 70kDa Protein 8, His-tagged

• Cat.No.: HSPA8-4712H
• Product Overview: Recombinant Human HSC70 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 666 amino acids (1-646 a.a.) and having a molecular mass of 73.1kDa. HSC70 human recombinant is fused to 20 amino acid His Tag at N-terminus and purified by convential chromatogrpahy techniques.

Specification

• Cat. No.: HSPA8-4712H
• Description: HSPA8 is part of the heat shock protein 70 family which includes both heat-inducible and constitutively expressed proteins (heat-shock cognate proteins). HSPA8 is a heat-shock cognate protein that binds to nascent polypeptides to facilitate correct folding. HSPA8 is directly linked with Influenza virus matrix protein 1 and thus required for viral production.
• Source: Human
• Host: Escherichia Coli.
• Form: The HSC70 protein solution contains 20mM Tris, pH-8 & 10% Glycerol.
• Purity: Greater than 90.0% as determined by SDS-PAGE.

Q&As

In the context of cellular stress, how does HSPA8 contribute to the heat shock response, and what downstream signaling pathways does it modulate to promote cell survival?

HSPA8 is a central player in the heat shock response, assisting in the refolding of denatured proteins. It modulates downstream pathways such as HSF1 activation, orchestrating a cellular survival response.

Can you discuss the involvement of HSPA8 in neurodegenerative diseases, and how does its chaperone activity influence protein aggregation and neuronal dysfunction?

HSPA8 plays a role in neurodegenerative diseases, mitigating protein aggregation and neuronal dysfunction. Its chaperone activity is crucial for maintaining protein homeostasis in the nervous system.

How does HSPA8 participate in the regulation of apoptosis, and what anti-apoptotic mechanisms does it employ to maintain cellular viability under stress conditions?

HSPA8 exhibits anti-apoptotic functions by interacting with pro-apoptotic proteins and preventing their activation. Its role in apoptosis regulation contributes to cell survival during stress.

What is the significance of HSPA8 in autophagy, and how does it influence the selective degradation of misfolded proteins and damaged organelles?

HSPA8 is involved in autophagy, facilitating the clearance of misfolded proteins and damaged organelles. It interacts with autophagy receptors, promoting their recognition by autophagosomes.

What are the mechanisms by which HSPA8 regulates the immune response, particularly its involvement in antigen presentation and the modulation of immune cell functions?

HSPA8 participates in antigen presentation and modulates immune cell functions. It chaperones antigens for presentation on major histocompatibility complexes, influencing immune recognition and response.
