{"rfam": {"acc": "RF00580", "id": "SNORD91", "description": "Small nucleolar RNA SNORD91 family", "comment": "The members of this family belong to the C/D class of snoRNAs which contain the 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 [1]. This family includes HBII-296A (SNORD91A) and HBII-296B (SNORD91B). They are close paralogues and share the same host gene (FLJ10534). Both snoRNAs and are predicted to guide 2'O-ribose methylation of the large 28S rRNA at position G4588 [3].", "curation": {"author": "Marantidis E, Daub J", "seed_source": "Marantidis E, INFERNAL", "num_seed": 24, "num_full": 977, "num_species": 495, "type": "Gene; snRNA; snoRNA; CD-box;", "structure_source": "Predicted; RNAalifold_manual; Daub J"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 31.03 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 51.0, "trusted": 51.1, "noise": 50.9}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": null, "id": null}}}
