Development of a fluorescence screening assay for binding partners of the iron-sulfur mitochondrial protein mitoNEET.

MitoNEET belongs to the CDGSH Iron-Sulfur Domain (CISD)-gene family of proteins and is a [2Fe-2S] cluster-containing protein found on the outer membrane of mitochondria. The specific functions of mitoNEET/CISD1 remain to be fully elucidated, but the protein is involved in regulating mitochondrial bioenergetics in several metabolic diseases. Unfortunately, drug discovery efforts targeting mitoNEET to improve metabolic disorders are hampered by the lack of ligand-binding assays for this mitochondrial protein.

Biochemical Control of the Mitochondrial Protein MitoNEET by Biological Thiols and Lipid-derived Electrophiles.

MitoNEET is a mitochondrial [2Fe-2S] protein known for its involvement in cellular metabolism, iron regulation, and oxidative stress. The protein has been associated with diseases ranging from diabetes to Parkinson's disease which has prompted development of compounds designed to selectively target mitoNEET. Unfortunately, drug development is limited due to a lack of understanding on the mechanistic level how mitoNEET integrates into pathophysiological processes.

The Mitochondrial Protein MitoNEET as a Probe for the Allostery of Glutamate Dehydrogenase.

The proteins glutamate dehydrogenase (GDH) and mitoNEET are both targets of drug development efforts to treat metabolic disorders, cancer, and neurodegenerative diseases. However, these two proteins differ starkly in the current knowledge about ligand binding sites. MitoNEET is a [2Fe-2S]-containing protein with no obvious binding site for small ligands observed in its crystal structures.

MitoNEET's Reactivity of Lys55 toward Pyridoxal Phosphate Demonstrates its Activity as a Transaminase Enzyme.

MitoNEET is a [2Fe-2S] redox active mitochondrial protein belonging to the CDGSH iron-sulfur domain (CISD) family of proteins. MitoNEET has been implicated as a potential target for drug development to treat various disorders, including type-2 diabetes, cancer, and Parkinson's disease. However, the specific cellular function(s) for mitoNEET still remains to be fully elucidated, and this presents a significant roadblock in rational drug development.
