CC -!- FUNCTION: Mitochondrial intermembrane chaperone that participates in
CC the import and insertion of some multi-pass transmembrane proteins into
CC the mitochondrial inner membrane. Also 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. The TIM8-
CC TIM13 complex is non essential and only mediates the import of few
CC proteins, while the predominant TIM9-TIM10 70 kDa complex is crucial
CC and mediates the import of much more proteins (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Heterohexamer; composed of 3 copies of TIM8 and 3 copies of
CC TIM13, named soluble 70 kDa complex. Associates with the TIM22 complex,
CC whose core is composed of TIM22 and TIM54. Interacts with the
CC transmembrane regions of multi-pass transmembrane proteins in transit
CC (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}; Intermembrane side
CC {ECO:0000250}.
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 TIM13 from cytoplasm into mitochondrion, the Cys
CC residues probably coordinate zinc, thereby preventing folding and
CC allowing its transfer across mitochondrial outer membrane (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the small Tim family. {ECO:0000305}.
