CC   -!- FUNCTION: May be a ribosome silencing factor (Potential). Involved in
CC       plastid biogenesis. Plastids affected by a mutation in Iojap lose the
CC       ability to perform translation and lack plastid ribosomes.
CC       {ECO:0000269|PubMed:1382980, ECO:0000305}.
CC   -!- SUBUNIT: Interacts with chloroplast ribosomal protein L14 (rpl14).
CC       {ECO:0000269|PubMed:22829778}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000305}.
CC   -!- DISRUPTION PHENOTYPE: Plastids lose the ability to perform translation
CC       and lack plastid ribosomes. {ECO:0000269|PubMed:1382980}.
CC   -!- SIMILARITY: Belongs to the Iojap/RsfS family. {ECO:0000305}.
