CC   -!- FUNCTION: One of the primary rRNA binding proteins, it binds
CC       directly to 16S rRNA where it nucleates assembly of the body of
CC       the 30S subunit (By similarity).
CC   -!- FUNCTION: With S5 and S12 plays an important role in translational
CC       accuracy (By similarity).
CC   -!- SUBUNIT: Part of the 30S ribosomal subunit. Contacts protein S5.
CC       The interaction surface between S4 and S5 is involved in control
CC       of translational fidelity (By similarity).
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the ribosomal protein S4P family.
CC   -!- SIMILARITY: Contains 1 S4 RNA-binding domain.
