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

Essential protein of the mitochondrial intermembrane space; forms a complex with Tim10p (TIM10 complex) that delivers hydrophobic proteins to the TIM22 complex for insertion into the inner membrane

Biogenesis of the essential Tim9-Tim10 chaperone complex of mitochondria: site-specific recognition of cysteine residues by the intermembrane space receptor Mia40.

Milenkovic D, Gabriel K, Guiard B, Schulze-Specking A, Pfanner N, Chacinska A

The mitochondrial intermembrane space (IMS) contains an essential machinery for protein import and assembly (MIA). Biogenesis of IMS proteins involves a disulfide relay between precursor proteins, the cysteine-rich IMS protein Mia40 and the sulfhydryl oxidase Erv1. How precursor proteins are specifically directed to the IMS has remained unknown. Here we systematically analyzed the role of cysteine residues in the biogenesis ... [more]

MIA40 TIM9
Affinity Capture-Western
Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
