CC   -!- FUNCTION: Binds as a heterodimer with protein S6 to the central domain
CC       of the 16S rRNA, where it helps stabilize the platform of the 30S
CC       subunit. {ECO:0000255|HAMAP-Rule:MF_00270}.
CC   -!- SUBUNIT: Part of the 30S ribosomal subunit. Forms a tight heterodimer
CC       with protein S6. {ECO:0000255|HAMAP-Rule:MF_00270}.
CC   -!- SIMILARITY: Belongs to the bacterial ribosomal protein bS18 family.
CC       {ECO:0000255|HAMAP-Rule:MF_00270}.
