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}.
