BAIT

MIA40

FMP15, TIM40, YKL195W
Mitochondrial oxidoreductase; involved in mitochondrial intermembrane space import; component of MIA pathway which mediates import and oxidative folding of substrates including small proteins containing twin cysteine motifs; acts in concert with Erv1p, which oxidizes the cysteine residues of Mia40p to comprise a disulfide relay system that catalyzes import; also mediates folding of Atp23p via a chaperone-like activity; forms a dimer that binds iron-sulfur cluster in vitro

TIM10

MRS11, protein transporter TIM10, L000003574, YHR005C-A
Essential protein of the mitochondrial intermembrane space; forms a complex with Tim9p (TIM10 complex) that delivers hydrophobic proteins to the TIM22 complex for insertion into the inner membrane

Biochemical Activity

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Structural and functional roles of the conserved cysteine residues of the redox-regulated import receptor Mia40 in the intermembrane space of mitochondria.

Terziyska N, Grumbt B, Kozany C, Hell K

Oxidative folding drives the import of proteins containing twin CXnC motifs into the intermembrane space of mitochondria. This import pathway employs a disulfide relay system whose key components are the redox-regulated import receptor Mia40 and the thiol oxidase Erv1. Mia40 contains six cysteine residues in a CPC-CX9C-CX9C arrangement in a highly conserved domain. We show that this domain is sufficient ... [more]
