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}.
