Evol. 191:27-28(1994). 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.
