CC -!- FUNCTION: May participate in the translocation of transit peptide-
CC containing proteins across the mitochondrial inner membrane.
CC {ECO:0000250}.
CC -!- SUBUNIT: Part of the respiratory complex III. Interacts with TIM23-2
CC and the cytochrome c1 and c2 subunits of complex III.
CC {ECO:0000269|PubMed:22730406}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000305};
CC Single-pass membrane protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in leaves, sheath, flowers and buds.
CC Lower expression in roots and stems. {ECO:0000269|PubMed:22131050}.
CC -!- DISRUPTION PHENOTYPE: Strong lethality at the post-seedling stage.
CC {ECO:0000269|PubMed:22131050}.
CC -!- SIMILARITY: Belongs to the TIM21 family. {ECO:0000305}.
