The CDGSH iron sulfur domain are a group of iron-sulfur (2Fe-2S) clusters and a unique 39 amino acid CDGSH domain [C-X-C-X2-(S/T)-X3-P-X-C-D-G-(S/A/T)-H].

The CDGSH iron sulfur domain 1 protein (also referred to as mitoNEET) is an integral membrane protein located in the outer mitochondrial membrane and whose function may be to transport iron into the mitochondria.{{cite journal | vauthors = Paddock ML, Wiley SE, Axelrod HL, Cohen AE, Roy M, Abresch EC, Capraro D, Murphy AN, Nechushtai R, Dixon JE, Jennings PA | title = MitoNEET is a uniquely folded 2Fe 2S outer mitochondrial membrane protein stabilized by pioglitazone | journal = Proc.

The antidiabetic drug pioglitazone, in addition to binding to the nuclear receptor PPAR, also has been shown to bind mitoNEET with approximately equal affinity.{{cite journal | vauthors = Colca JR, McDonald WG, Waldon DJ, Leone JW, Lull JM, Bannow CA, Lund ET, Mathews WR | title = Identification of a novel mitochondrial protein ("mitoNEET") cross-linked specifically by a thiazolidinedione photoprobe | journal = Am.
