CC   -!- FUNCTION: This protein is responsible for splicing and maturation of
CC       cytochrome b mRNA. Specifically, it may be responsible for the splicing
CC       specificity of the second intron (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion.
CC   -!- MISCELLANEOUS: Encoded within intron 2 of COB.
CC   -!- SIMILARITY: Belongs to the LAGLIDADG endonuclease family.
CC       {ECO:0000305}.
