The human DNAJC6 protein, a member of the J-domain-containing cochaperone family (HSP40/DnaJ), plays a critical role in regulating HSP70 chaperone activity during protein folding, trafficking, and degradation. It is particularly vital in neuronal function, where it assists in clathrin-mediated endocytosis, synaptic vesicle recycling, and maintaining neurotransmitter release dynamics. Genetic mutations in DNAJC6 are linked to early-onset Parkinson’s disease (PD), often presenting with severe symptoms due to impaired synaptic vesicle trafficking and neuronal survival.
Recombinant human DNAJC6 protein is engineered using bacterial (e.g., E. coli) or mammalian expression systems (e.g., HEK293 cells) to produce soluble, functional forms for research. Its recombinant version enables studies on molecular mechanisms underlying PD pathogenesis, including misfolded protein aggregation, autophagy-lysosomal dysfunction, and dopaminergic neuron degeneration. Researchers also employ it to explore DNAJC6’s interaction with key partners like auxilin and AP-2 adaptors in endocytic pathways.
Current applications include in vitro assays to screen therapeutic compounds targeting DNAJC6-associated pathways, validate disease-causing variants via functional rescue experiments, and develop gene therapy strategies. Structural studies using recombinant DNAJC6 further aim to map functional domains and mutation hotspots. However, challenges persist in achieving proper post-translational modifications in recombinant forms, necessitating optimization for physiological relevance. Overall, this protein serves as a pivotal tool for unraveling neuroprotective mechanisms and advancing PD therapeutics.
