The human DNAJC8 protein, a member of the evolutionarily conserved DNAJ/Hsp40 family, functions as a co-chaperone for Hsp70 proteins to regulate protein folding, stability, and degradation. It contains a characteristic J-domain that facilitates interaction with Hsp70 ATPase, enabling substrate recognition and stress-response coordination. DNAJC8 is ubiquitously expressed, with notable roles in cellular processes like protein quality control, signal transduction, and apoptosis. Recent studies highlight its involvement in cancer progression, neurodegenerative disorders, and viral infection pathways, though its precise mechanisms remain under investigation. Recombinant DNAJC8 is typically produced in *E. coli* or mammalian expression systems, utilizing affinity tags (e.g., His-tag) for purification. This engineered protein serves as a critical tool for structural studies (e.g., X-ray crystallography), mapping interaction networks, and screening therapeutic compounds targeting chaperone-mediated diseases. Its dysregulation has been linked to chemoresistance in tumors and misfolded protein accumulation in Alzheimer’s models, underscoring potential therapeutic relevance. Ongoing research aims to delineate its substrate specificity and tissue-specific isoforms to advance precision medicine applications.
