Plays a key role in regulating maximal capacity for electron transport and oxidative phosphorylation. May be involved in Fe-S cluster shuttling and/or in redox reactions.
Regulator of autophagy that contributes to antagonize BECN1-mediated cellular autophagy at the endoplasmic reticulum. Participates in the interaction of BCL2 with BECN1 and is required for BCL2-mediated depression of endoplasmic reticulum Ca(2+) stores during autophagy. Contributes to BIK-initiated autophagy, while it is not involved in BIK-dependent activation of caspases. Involved in life span control, probably via its function as regulator of autophagy.

The CDGSH-type zinc finger domain binds iron rather than zinc as a redox-active pH-labile 2Fe-2S cluster. The conserved sequence C-X-C-X2-(S/T)-X3-P-X-C-D-G-(S/A/T)-H is a defining feature of this family. The domain is oriented towards the cytoplasm and is tethered to the mitochondrial membrane by a more N-terminal domain found in higher vertebrates, MitoNEET_N, pfam10660. The domain forms a uniquely folded homo-dimer and spans the outer mitochondrial membrane, orienting the iron-binding residues towards the cytoplasm. Length = 34
>PF09360 zf-CDGSH: Iron-binding zinc finger CDGSH type; InterPro: IPR018967 This entry represents iron-sulphur domain containing proteins that have a CDGSH sequence motif (although the Ser residue can also be an Ala or Thr), and is found in proteins from a wide range of organisms with the exception of fungi
The CDGSH-type domain binds a redox-active pH-labile 2Fe-2S cluster. The conserved sequence C-X-C-X2-(S/T)-X3-P-X-C-D-G-(S/A/T)-H is a defining feature of this family []. CDGSH-type domains are found in mitoNEET, an iron-containing integral protein of the outer mitochondrian membrane (OMM). MitoNEET forms a dimeric structure with a NEET fold, and contains two domains: a beta-cap region and a cluster-binding domain that coordinated two acid-labile 2Fe-2S clusters (one bound to each protomer) []. The CDGSH iron-sulphur domain is oriented towards the cytoplasm and is tethered to the mitochondrial membrane by a more N-terminal domain found in higher vertebrates, (IPR019610 from INTERPRO) [, ].

The CDGSH iron sulphur domain 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 []. Iron in turn is essential for the function of several mitochondrial enzymes. This entry represents the N-terminal of the mitoNEET and Miner-type proteins that carry a CDGSH-type cluster-binding domain (IPR018967 from INTERPRO) that coordinate a redox-active 2Fe-2S cluster. In the outer mitochondrian membrane (OMM), the CDGSH 2Fe-2S-containing domain is oriented towards the cytoplasm and is tethered to the mitochondrial membrane by the N-terminal domain found in higher vertebrates [, , ]. The whole protein regulates oxidative capacity and may function in electron transfer, for instance in redox reactions with metabolic intermediates, cofactors and/or proteins localized at the OMM.; GO: 0051537 2 iron, 2 sulfur cluster binding, 0043231 intracellular membrane-bounded organelle; PDB: 2R13_A 3REE_A 2QD0_B.
