CC   -!- FUNCTION: Binds the lower part of the 30S subunit head. Binds mRNA in
CC       the 70S ribosome, positioning it for translation. {ECO:0000255|HAMAP-
CC       Rule:MF_01309}.
CC   -!- SUBUNIT: Part of the 30S ribosomal subunit. Forms a tight complex with
CC       proteins S10 and S14. {ECO:0000255|HAMAP-Rule:MF_01309}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uS3 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01309}.
