CC   -!- FUNCTION: Involved in cytoplasmic male sterility (CMS) by leading to
CC       pollen abortion. Not expressed in fertile (normal) plants.
CC       {ECO:0000269|PubMed:8000006}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion membrane
CC       {ECO:0000269|PubMed:8000006}; Single-pass membrane protein
CC       {ECO:0000269|PubMed:8000006}.
CC   -!- TISSUE SPECIFICITY: Expressed in roots, leaves and flowers.
CC       {ECO:0000269|PubMed:8000006}.
CC   -!- MISCELLANEOUS: Nuclear restoration is accompanied by a dramatic
CC       reduction in the amount of this protein in mitochondria of flowers and
CC       leaves, but not roots of fertility-restored plants. The restorer genes
CC       are affecting either the translation or the stability of the protein.
