简介
The HSP70/HSPA1A protein is an important molecular chaperone that protects proteome integrity by counteracting stress, aiding protein folding, activating misfolded proteolysis, and regulating protein complex dynamics. In protein quality control systems, it ensures accurate protein folding, controls substrate targeting for degradation through the ATP cycle, and interacts with co-chaperones such as HSP40, BAG1/2/3, HOPX, and STUB1. HSP70/HSPA1A Protein, Human (E110D, His) is the recombinant human-derived HSP70/HSPA1A protein, expressed by E. coli , with N-His labeled tag and E110D mutation.

Protein Description
HSP70, specifically the HSPA1A isoform, is a heat shock protein that plays a critical role in cellular stress responses, protein folding, and protection against apoptosis. It functions as a molecular chaperone, facilitating the proper folding of nascent polypeptides and the refolding of misfolded proteins, thereby maintaining cellular homeostasis. The expression of HSPA1A is induced under stressful conditions, including heat shock, oxidative stress, and exposure to toxins, highlighting its essential role in protecting cells from damage. Research into HSP70/HSPA1A recombinant proteins has gained significant attention due to their potential therapeutic applications in various diseases, including cancer and neurodegenerative disorders. These studies focus on understanding the mechanistic pathways mediated by HSPA1A and exploring its role in modulating immune responses, cellular signaling, and apoptosis. By generating recombinant HSPA1A, researchers aim to investigate its efficacy as a vaccine adjuvant, diagnostic tool, and therapeutic agent. The ability to produce HSPA1A in a recombinant form allows for detailed biochemical studies and the development of potential interventions to enhance its protective functions in disease contexts. Furthermore, understanding the implications of HSP70/HSPA1A in cellular health and disease could lead to novel strategies for treating conditions associated with protein misfolding and aggregation. Overall, the study of HSP70/HSPA1A recombinant proteins is pivotal in advancing our knowledge of cell biology and developing innovative therapeutic approaches.
