Recombinant human DNAJC1 protein, also known as DnaJ homolog subfamily C member 1. is a member of the DNAJ/HSP40 family of molecular chaperones that regulate the ATPase activity of HSP70 proteins to facilitate protein folding, trafficking, and degradation. DNAJC1 is ubiquitously expressed and localizes primarily to the endoplasmic reticulum (ER) and mitochondria-associated membranes (MAMs). It plays a critical role in cellular stress responses, particularly in regulating ER stress, autophagy, and mitochondrial function. Structurally, it contains a conserved J-domain for HSP70 interaction, a transmembrane domain, and regions implicated in lipid binding. Dysregulation of DNAJC1 has been linked to neurodegenerative disorders, cancer, and metabolic diseases due to its involvement in proteostasis, apoptosis, and energy metabolism. Recombinant forms of DNAJC1 are engineered using expression systems (e.g., E. coli, mammalian cells) for in vitro studies to explore its biochemical interactions, structural properties, and therapeutic potential. Current research focuses on its role in mitigating protein aggregation in Alzheimer’s and Parkinson’s diseases, modulating cancer cell survival under stress, and maintaining mitochondrial integrity in metabolic syndromes. This protein serves as a key experimental tool for elucidating molecular mechanisms of chaperone networks and stress adaptation.
