RT "Crystal structure of the mitochondrial chaperone TIM9.10 reveals a six-
RT bladed alpha-propeller.";
RL Mol. Cell 21:123-133(2006).
CC -!- FUNCTION: Mitochondrial intermembrane chaperone that participates in
CC the import and insertion of multi-pass transmembrane proteins into the
CC mitochondrial inner membrane. May also be required for the transfer of
CC beta-barrel precursors from the TOM complex to the sorting and assembly
CC machinery (SAM complex) of the outer membrane. Acts as a chaperone-like
CC protein that protects the hydrophobic precursors from aggregation and
CC guide them through the mitochondrial intermembrane space.
CC {ECO:0000269|PubMed:14726512}.
CC -!- SUBUNIT: Heterohexamer; composed of 3 copies of TIMM9 and 3 copies of
CC TIMM10/TIM10A, named soluble 70 kDa complex. The complex forms a 6-
CC bladed alpha-propeller structure and associates with the TIMM22
CC component of the TIM22 complex. Interacts with multi-pass transmembrane
CC proteins in transit. Also forms a complex composed of TIMM9,
CC TIMM10/TIM10A and FXC1/TIM10B. {ECO:0000269|PubMed:14726512,
CC ECO:0000269|PubMed:16387659}.
CC -!- INTERACTION:
CC Q9Y5J7; P62072: TIMM10; NbExp=5; IntAct=EBI-1200370, EBI-1200391;
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:11489896, ECO:0000269|PubMed:14726512}; Peripheral
CC membrane protein {ECO:0000269|PubMed:11489896,
CC ECO:0000269|PubMed:14726512}; Intermembrane side
CC {ECO:0000269|PubMed:11489896, ECO:0000269|PubMed:14726512}.
CC -!- TISSUE SPECIFICITY: Ubiquitous, with highest expression in heart,
CC kidney, liver and skeletal muscle. {ECO:0000269|PubMed:10552927,
CC ECO:0000269|PubMed:10611480}.
CC -!- DOMAIN: The twin CX3C motif contains 4 conserved Cys residues that form
CC 2 disulfide bonds in the mitochondrial intermembrane space. However,
CC during the transit of TIMM9 from cytoplasm into mitochondrion, the Cys
CC residues probably coordinate zinc, thereby preventing folding and
CC allowing its transfer across mitochondrial outer membrane (Probable).
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the small Tim family. {ECO:0000305}.
