Comments [?]

Function One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.
With S5 and S12 plays an important role in translational accuracy.
Subunit Part of the 30S ribosomal subunit. Contacts protein S5. The interaction surface between S4 and S5 is involved in control of translational fidelity.
case <OG:Chloroplast>
Subcellular location Plastid, chloroplast.
end case
Similarity Belongs to the ribosomal protein S4P family.

Comments Some plastid-encoded rps4 sequences (EIMTE, HELSJ, STIHETOXGO), as well as CARRP and NEOSM are quite divergent and thus have been made atypical. The second and third copies in the Clostridia have also been made atypical. In AZOSB the second copy is truncated and probably not functional.
