HSP70 Protein

Human Recombinant HSP70 Full Length Protein

Product Specifications

Background

HSP70 is a highly inducible molecular chaperone that plays a pivotal role in protein quality control across all major cellular compartments. In the brain, HSP70 is essential for preventing the aggregation of misfolded proteins, a key pathological feature of neurodegenerative diseases. HSP70 binds to nascent and partially folded polypeptides, stabilizing them and facilitating proper folding or directing them toward degradation pathways. This function is particularly critical in conditions such as Alzheimer’s, Parkinson’s, and ALS, where protein aggregation and impaired proteostasis drive neuronal dysfunction and cell death. The chaperone activity of HSP70 is regulated by ATP binding and hydrolysis, which triggers conformational changes that control substrate binding and release. Its ability to recognize hydrophobic regions of unfolded proteins enables it to suppress aggregation and promote cellular recovery from stress. Therapeutic strategies aimed at enhancing HSP70 expression or activity are under investigation for their potential to reduce neurotoxicity, improve protein clearance, and slow disease progression in neurodegenerative disorders.
