CC   -!- FUNCTION: This is one of the proteins that binds and probably mediates
CC       the attachment of the 5S RNA into the large ribosomal subunit, where it
CC       forms part of the central protuberance. {ECO:0000255|HAMAP-
CC       Rule:MF_01337}.
CC   -!- SUBUNIT: Part of the 50S ribosomal subunit; part of the 5S
CC       rRNA/L5/L18/L25 subcomplex. Contacts the 5S and 23S rRNAs.
CC       {ECO:0000255|HAMAP-Rule:MF_01337}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uL18 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01337}.
