CC   -!- FUNCTION: One of the primary rRNA binding proteins, it binds directly
CC       to 16S rRNA where it nucleates assembly of the body of the 30S subunit.
CC       {ECO:0000250}.
CC   -!- FUNCTION: With S5 and S12 plays an important role in translational
CC       accuracy. {ECO:0000250}.
CC   -!- SUBUNIT: Part of the 30S ribosomal subunit. Contacts protein S5. The
CC       interaction surface between S4 and S5 is involved in control of
CC       translational fidelity (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uS4 family.
CC       {ECO:0000305}.
