The human sequence has also been annotated in the sequence databases as U46. U40 is encoded in intron 2 of the ribosomal protein S8 gene in human, and is hypothesised to guide methylation of 2'-O-ribose residues on 28S ribosomal RNA [1]. This family represents vertebrate U40.", "curation": {"author": "Griffiths-Jones SR, Eberhardt R", "seed_source": "Griffiths-Jones SR", "num_seed": 5, "num_full": 723, "num_species": 611, "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 22.00 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 40.0, "trusted": 40.0, "noise": 39.8}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": "CL00061", "id": "SNORD46"}}}
