Protein attributes

Sequence length	209 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (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 By similarity. HAMAP-Rule MF_01306 With S5 and S12 plays an important role in translational accuracy By similarity. HAMAP-Rule MF_01306
Subunit structure	Part of the 30S ribosomal subunit. Contacts protein S5. The interaction surface between S4 and S5 is involved in control of translational fidelity By similarity.
Sequence similarities	Belongs to the ribosomal protein S4P family. Contains 1 S4 RNA-binding domain.
