CISD1 (CDGSH Iron-Sulfur Domain-Containing Protein 1), also known as mitoNEET, is a mitochondrial outer membrane protein belonging to the NEET protein family. It features a unique CDGSH domain that coordinates a redox-active [2Fe-2S] cluster, crucial for its biological functions. Structurally, it forms a homodimer through its β-cap domain, enabling interaction with various molecular partners.
Discovered in 2007 through drug-target interaction studies, CISD1 plays pivotal roles in cellular iron homeostasis, redox regulation, and mitochondrial energy metabolism. It participates in iron-sulfur (Fe-S) cluster transfer between mitochondria and cytosol, influencing electron transport chain efficiency. The protein also modulates reactive oxygen species (ROS) levels and maintains mitochondrial membrane potential, thereby regulating apoptosis and mitophagy.
Recombinant CISD1 production typically involves bacterial expression systems (e.g., E. coli) with optimized conditions for proper Fe-S cluster incorporation. Purification methods often exploit its heat-stable nature and affinity tags. Studies using recombinant CISD1 have revealed its pH-sensitive cluster release mechanism and interaction with nutrients/metabolites.
Pathologically, CISD1 dysfunction links to metabolic disorders, neurodegeneration, and cancer. Its overexpression in certain cancers correlates with chemoresistance, while mutations cause Wolfram syndrome type 2. Recombinant CISD1 serves as a valuable tool for structural studies, drug screening (particularly for diabetes and cancer therapies), and elucidating mitochondrial pathophysiology. Current research explores its potential as a therapeutic target for metabolic syndrome and age-related diseases through Fe-S cluster-mediated regulatory mechanisms.
