Protein CutA (CUTA) Protein

Background

The cutA divalent cation tolerance homolog (CUTA) is a highly conserved protein that plays a role in cellular tolerance to divalent metal cations, such as copper, zinc, and nickel. It is ubiquitously expressed in various tissues and is localized in both the cytoplasm and mitochondria, where it is thought to regulate metal ion homeostasis and protect cells from metal-induced toxicity. CUTA is implicated in modulating mitochondrial function and redox balance by ensuring appropriate cation levels, which are essential for enzymatic activities and structural stability within the organelle. Dysregulation of CUTA expression or function has been associated with mitochondrial dysfunction and oxidative stress, which are linked to neurodegenerative diseases, including Alzheimer's disease. CUTA has also been suggested to have a role in copper homeostasis, as it may influence copper-binding proteins and prevent copper-induced oxidative damage. Although its precise mechanisms of action remain under investigation, CUTA's involvement in metal ion detoxification and mitochondrial health makes it a potential target for understanding and treating conditions associated with metal ion imbalance.
