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: Homomultimer. Component of the TIM17:23 complex at least
CC composed of TIM23, TIM17 and TIM50. The complex interacts with the
CC TIM44 component of the PAM complex. Also part of the NADH-ubiquinone
CC oxidoreductase complex I. Interacts with OEP163, TIM17-2, TIM21, TIM50
CC and MPPA2. {ECO:0000269|PubMed:22730406}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000305};
CC Multi-pass membrane protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in roots and young cotyledons. Detected
CC in leaves and flowers. {ECO:0000269|PubMed:12692332,
CC ECO:0000269|PubMed:14730085}.
CC -!- DEVELOPMENTAL STAGE: Peak of expression during cotyledon development.
CC {ECO:0000269|PubMed:12692332}.
CC -!- DOMAIN: The C-terminal part (143-188) is required for insertion in the
CC mitochondrial inner membrane.
CC -!- SIMILARITY: Belongs to the Tim17/Tim22/Tim23 family. {ECO:0000305}.
