CC -!- FUNCTION: Essential component of the TIM23 complex, a complex that CC mediates the translocation of transit peptide-containing proteins CC across the mitochondrial inner membrane. CC {ECO:0000256|RuleBase:RU364003}. CC -!- SUBUNIT: Component of the TIM23 complex at least composed of CC TIMM23, TIMM17 (TIMM17A or TIMM17B) and TIMM50. CC {ECO:0000256|RuleBase:RU364003}. CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane CC {ECO:0000256|RuleBase:RU364003}; Multi-pass membrane protein CC {ECO:0000256|RuleBase:RU364003}. CC -!- SIMILARITY: Belongs to the Tim17/Tim22/Tim23 family. CC {ECO:0000256|RuleBase:RU364003}.
