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 (By
CC       similarity). {ECO:0000250}.
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 (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 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}.
