CC -!- FUNCTION: Essential core component of the TIM22 complex, a complex that
CC mediates the import and insertion of multi-pass transmembrane proteins,
CC such as mitochondrial carrier family members, into the mitochondrial
CC inner membrane. In the TIM22 complex, it constitutes the voltage-
CC activated and signal-gated channel. Forms a twin-pore translocase that
CC uses the membrane potential as external driving force in 2 voltage-
CC dependent steps. Mediates the insertion of precursor proteins in a 3
CC step process. After the precursor is tethered to the translocase
CC without losing energy from the Delta(psi), 2 energy-requiring steps are
CC needed. First, Delta(psi) acts on the precursor protein and promotes
CC its docking in the translocase complex. Then, Delta(psi) and an
CC internal signal peptide together induce rapid gating transitions in one
CC pore and closing of the other pore and drive membrane insertion to
CC completion. {ECO:0000269|PubMed:11864609, ECO:0000269|PubMed:12637749,
CC ECO:0000269|PubMed:8955274}.
CC -!- SUBUNIT: Component of the TIM22 complex, whose core is composed of
CC TIM18, TIM22 and TIM54, associated with the peripheral proteins
CC MRS5/TIM12 and the 70 kDa heterohexamer composed of TIM9 and TIM10 (or
CC TIM8 and TIM13). {ECO:0000269|PubMed:10648604,
CC ECO:0000269|PubMed:12637749}.
CC -!- INTERACTION:
CC Q12328; P53220: TIM21; NbExp=2; IntAct=EBI-9132, EBI-23128;
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:10397776, ECO:0000269|PubMed:8955274,
CC ECO:0000305|PubMed:27265872}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:10397776, ECO:0000269|PubMed:8955274}. Note=Import
CC into inner membrane protein requires TOM20 function.
CC -!- SIMILARITY: Belongs to the Tim17/Tim22/Tim23 family. {ECO:0000305}.
