CC   -!- FUNCTION: Essential core component of the TIM22 complex, a complex that
CC       mediates the import and insertion of multi-pass transmembrane proteins
CC       into the mitochondrial inner membrane. In the TIM22 complex, it
CC       constitutes the voltage-activated and signal-gated channel. Forms a
CC       twin-pore translocase that uses the membrane potential as external
CC       driving force in 2 voltage-dependent steps (By similarity).
CC       {ECO:0000250|UniProtKB:Q12328}.
CC   -!- SUBUNIT: Component of the TIM22 complex, whose core is composed of
CC       TIM22 and TIM54, associated with the 70 kDa heterohexamer composed of
CC       TIM9 and TIM10 (or TIM8 and TIM13). {ECO:0000250|UniProtKB:Q12328}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:Q12328}; Multi-pass membrane protein
CC       {ECO:0000255}.
CC   -!- SIMILARITY: Belongs to the Tim17/Tim22/Tim23 family. {ECO:0000305}.
