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:0000256|HAMAP-Rule:MF_01306}.
CC -!- FUNCTION: With S5 and S12 plays an important role in translational
CC accuracy. {ECO:0000256|HAMAP-Rule:MF_01306}.
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. {ECO:0000256|HAMAP-Rule:MF_01306}.
CC -!- SIMILARITY: Belongs to the universal ribosomal protein uS4 family.
CC {ECO:0000256|ARBA:ARBA00007465, ECO:0000256|HAMAP-Rule:MF_01306}.
