UniProt Comments
Nuclear genome-encoded factor involved in ribosome biogenesis in chloroplasts (PubMed:22576849, PubMed:23227895, PubMed:25043599). Binds specific group II introns in chloroplasts and facilitates their splicing. Is required for rRNA maturation in plastids and may contribute to the assembly of the large (50S) ribosomal subunit (PubMed:22576849). Required for normal development of chloroplasts (PubMed:22576849, PubMed:23227895, PubMed:25043599). Required for the expression of transcripts encoding plastid-localized enzymes involved in abscisic acid (ABA) biosynthesis. Required for maintenance of ABA levels and response to salt stress (PubMed:23227895). Possesses RNA chaperone activity for proper splicing of introns in chloroplasts. Essential for chloroplast function and abiotic stress responses (PubMed:25043599).
