{"rfam": {"acc": "RF00221", "id": "SNORD43", "description": "Small nucleolar RNA SNORD43", "comment": "U43 is a C/D box small nucleolar RNA that is encoded in intron 1 of the ribosomal protein L3 gene in human and cow [2]. Three other snoRNAs ( U82, U83a and U83b) are also encoded in the same host gene but from different introns [2]. The rice homologue is expressed from a cluster also containing snoR16 [1]. The Arabidopsis homologue is annotated as snoR41 in the sequence databases. U43 is hypothesised to guide methylation of 2'-O-ribose residues on 18S ribosomal RNA [1]. This family represents mammalian U43.", "curation": {"author": "Griffiths-Jones SR, Eberhardt R", "seed_source": "Griffiths-Jones SR", "num_seed": 4, "num_full": 264, "num_species": 132, "type": "Gene; snRNA; snoRNA; CD-box;", "structure_source": "Predicted; Griffiths-Jones SR"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 18.00 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 45.0, "trusted": 45.7, "noise": 44.9}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": "CL00059", "id": "SNORD43"}}}
