CC   -!- FUNCTION: Has a role in mitochondrial fission. Has a role in outer
CC       membrane fission but not matrix separation (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane {ECO:0000250};
CC       Single-pass membrane protein {ECO:0000250}.
CC   -!- DOMAIN: The C-terminus is required for mitochondrial localization,
CC       while the N-terminus is necessary for mitochondrial fission.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the FIS1 family. {ECO:0000305}.
