CC   -!- FUNCTION: Binds to 23S rRNA. {ECO:0000250}.
CC   -!- SUBUNIT: Part of the 50S ribosomal subunit. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uL23 family.
CC       {ECO:0000305}.
CC   -!- CAUTION: Could be the product of a pseudogene. RPL23 has been split
CC       into 2 overlapping ORFs in the Caryophyllales. Although these genes are
CC       transcribed, this is probably the product of a pseudogene; the protein
CC       purified with the 50S subunit is the product of a nuclear-encoded gene
CC       (AC Q9LWB5). {ECO:0000305}.
