Modeling onto the 70S spinach chloroplast ribosome and its position in the E.coli 70S ribosome suggests it binds in the decoding region of the 30S ribosomal subunit, precluding the binding of tRNA to the ribosome. Its position is incompatible with translation. Upon expression in E.coli binds to 30S and 70S ribosomes, decreases binding of tRNA(fMet). Stabilizes 70S ribosomes against dissociation. May be recycled by the combined action of ribosome-recycling factor (RRF) and EF-G.<ref>PMID:19965869</ref> [[http://www.uniprot.org/uniprot/RR12_SPIOL RR12_SPIOL]] With S4 and S5 plays an important role in translational accuracy.
