CC   -!- FUNCTION: This protein binds specifically to 23S rRNA. {ECO:0000250}.
CC   -!- FUNCTION: The globular domain of the protein is located near the
CC       polypeptide exit tunnel on the outside of the subunit, while an
CC       extended beta-hairpin is found that lines the wall of the exit tunnel
CC       in the center of the 70S ribosome. {ECO:0000250}.
CC   -!- SUBUNIT: Part of the 50S ribosomal subunit.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uL22 family.
CC       {ECO:0000305}.
