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 -!- SUBCELLULAR LOCATION: Plastid, chloroplast. CC -!- SIMILARITY: Belongs to the universal ribosomal protein uS4 family. CC {ECO:0000305}.
