Members of this family belong to the C/D box class of snoRNA which contain C (UGAUGA) and D (CUGA) box motifs. Most of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs. snoZ196 acts as a methylation guide for 18S ribosomal RNA in plants [1].Although the selection of the target nucleotide requires the antisense element and the conserved box D or D' of the snoRNA, the methyltransferase activity is supposed to reside in one of the protein components [4].", "curation": {"author": "Moxon SJ, Daub J", "seed_source": "Griffiths-Jones SR", "num_seed": 22, "num_full": 837, "num_species": 232, "type": "Gene; snRNA; snoRNA; CD-box;", "structure_source": "Predicted; PFOLD"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 31.25 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 55.0, "trusted": 55.0, "noise": 54.9}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": "CL00054", "id": "SNORD33"}}}
