CC -!- FUNCTION: Essential component of the TIM17:23 complex, a complex that
CC mediates the translocation of transit peptide-containing proteins
CC across the mitochondrial inner membrane. Links the inner and outer
CC membranes (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the TIM17:23 complex at least composed of TIM23,
CC TIM17 and TIM50. The complex interacts with the TIM44 component of the
CC PAM complex (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000305};
CC Multi-pass membrane protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, flowers, cotyledons and leaves.
CC {ECO:0000269|PubMed:12692332, ECO:0000269|PubMed:14730085}.
CC -!- DEVELOPMENTAL STAGE: Peak of expression during cotyledon development.
CC {ECO:0000269|PubMed:12692332}.
CC -!- SIMILARITY: Belongs to the Tim17/Tim22/Tim23 family. {ECO:0000305}.
