CC   -!- FUNCTION: Component of the TIM22 complex, a complex that mediates the
CC       import and insertion of multi-pass transmembrane proteins into the
CC       mitochondrial inner membrane. The TIM22 complex forms a twin-pore
CC       translocase that uses the membrane potential as the external driving
CC       force. In the TIM22 complex, it may act as a docking point for the
CC       soluble 70 kDa complex that guides the target proteins in transit
CC       through the aqueous mitochondrial intermembrane space.
CC       {ECO:0000269|PubMed:14726512}.
CC   -!- SUBUNIT: Component of the TIM22 complex, which core is composed of
CC       TIMM22, associated with TIMM10 (TIMM10A and/or TIMM10B), TIMM9, AGK and
CC       TIMM29 (PubMed:28712724). {ECO:0000269|PubMed:14726512,
CC       ECO:0000269|PubMed:28712724}.

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}.
CC   -!- TISSUE SPECIFICITY: Ubiquitous, with highest expression in heart,
CC       kidney, liver and skeletal muscle. {ECO:0000269|PubMed:10611480,
CC       ECO:0000269|PubMed:14726512}.
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 TIMM10B from cytoplasm into mitochondrion, the
CC       Cys residues probably coordinate zinc, thereby preventing folding and
CC       allowing its transfer across mitochondrial outer membrane.
CC       {ECO:0000250|UniProtKB:P87108}.
CC   -!- SIMILARITY: Belongs to the small Tim family. {ECO:0000305}.
