| Function: | |
Ribosome-binding factor involved in light- and temperature- dependent control of protein synthesis. Interacts with 16S sRNA nucleotides at the A-site and P-site, where it protects the decoding center and inhibits translation by preventing tRNA binding. Stabilizes 70S ribosomes against dissociation. May be recycled by the combined action of ribosome-recycling factor (RRF) and EF-G. {ECO:0000269|PubMed:19965869, ECO:0000269|PubMed:28007896}. |

| Subunit: | |
Binds to the mRNA channel of the chloroplast small ribosomal subunit and interacts with 16S sRNA nucleotides at the A-site and P- site. {ECO:0000269|PubMed:28007896}. |
