UniProtKB description:  Involved in chloroplast mRNA stability (PubMed:19424177, PubMed:21173259, PubMed:22156165). Binds specifically to two intergenic RNA regions of similar sequence located in the chloroplast atpH 5'-UTR and psaJ 3'-UTR, and serves as a barrier to RNA decay (PubMed:19424177). Binding to a specific site in the intergenic region of the chloroplast atpH is sufficient to block 5'-3' and 3'-5' exonucleases (PubMed:21173259). Acts as a protein barrier to block mRNA degradation by exonucleases, and defines processed mRNA termini in chloroplasts (PubMed:22156165). Remodels the structure of the atpH ribosome-binding site in a manner that can account for its ability to enhance translation (PubMed:21173259). Stabilizes a RNA 3'-end downstream from psaI (PubMed:30125002). Binds atpH RNA as a monomer (PubMed:25609698).
